CVE-2026-54357 WRITEUP MEDIUM WRITEUP
MISP improper authorization allows organization administrators to modify site administrator user settings
An improper authorization vulnerability in MISP allowed an authenticated organization administrator to access or modify user settings belonging to site administrator accounts within the same organization. The affected access-control checks scoped administrative actions by organization membership but did not exclude higher-privileged site administrator users. As a result, an organization administrator could potentially view or alter site administrator user settings and related login profile information, crossing the intended privilege boundary between organization administration and site-wide administration. The patch hardens the ACL logic by excluding site administrator accounts from organization administrator–managed user sets, adding explicit authorization failure when a target user is not administrable, and ensuring user setting and login profile operations fail closed.
CVE-2026-54358 WRITEUP HIGH WRITEUP
MISP organization administrators can target site administrator accounts for password reset
An incorrect authorization vulnerability in MISP allows an organization administrator to target site administrator accounts belonging to the same organization through the administrative email functionality. The affected code restricted organization administrators to users within their own organization, but did not exclude accounts assigned a site administrator role from recipient queries. As a result, an organization administrator could perform privileged account-management actions, such as initiating a password reset workflow, against a higher-privileged site administrator account in the same organization. Successful exploitation may allow an authenticated organization administrator to interfere with or potentially take over a site administrator account, resulting in privilege escalation and full compromise of the MISP instance’s confidentiality, integrity, and availability. Attack prerequisites: The attacker must be authenticated as an organization administrator in the same organization as a site administrator account.
CVE-2026-54359 WRITEUP HIGH WRITEUP
MISP automation endpoints may be exposed to CSRF when Sec-Fetch-Site protection is disabled by default
MISP contains an insecure default configuration in which the Security.check_sec_fetch_site_header control is disabled. When this setting is disabled, state-changing requests such as POST, PUT, or AJAX requests are not restricted based on the browser-provided Sec-Fetch-Site header. A remote unauthenticated attacker could craft a malicious web page that causes an authenticated MISP user’s browser to issue cross-site requests to MISP automation endpoints. If successful, the forged requests may be processed with the privileges of the victim user, potentially allowing unauthorized modification of MISP data or configuration. Enabling Security.check_sec_fetch_site_header mitigates this issue, although operators of multi-homed MISP deployments should validate the setting before enforcing it.
CVE-2026-54360 WRITEUP HIGH WRITEUP
MISP sharing group creation mass assignment allows unauthorized takeover of existing sharing groups
A mass assignment vulnerability exists in MISP’s sharing group creation endpoint. When creating a new sharing group, the controller did not remove a user-supplied id field before saving the submitted data. In CakePHP, supplying a primary key in the save data can cause a create() followed by save() operation to update an existing record instead of creating a new one. An authenticated user with permission to add sharing groups could therefore submit the identifier of an existing sharing group and modify that sharing group without passing the normal edit access-control checks. This may allow the attacker to take over or alter sharing groups they do not otherwise have access to, potentially affecting the confidentiality and integrity of information shared through those groups. Affected component: app/Controller/SharingGroupsController.php, add() action
CVE-2026-54361 WRITEUP HIGH WRITEUP
MISP mass assignment vulnerabilities allow unauthorized modification of ownership and delegation records
MISP contained multiple mass assignment vulnerabilities in the handling of collections, tag collections, event delegations, and shadow attributes. Several controller actions accepted user-supplied fields that should have remained server-controlled, including record identifiers and ownership-related fields such as id, org_id, orgc_id, and user_id. An authenticated attacker with access to the affected endpoints could craft requests containing protected fields in order to alter object ownership, redirect an update to another record, overwrite existing event delegation requests, or modify shadow attribute proposals belonging to another organization. This could result in unauthorized modification of MISP objects and, depending on object visibility and sharing configuration, unauthorized access to or transfer of sensitive threat intelligence data. The issue was fixed by explicitly pinning ownership and identity fields to their stored values during edit operations and by removing user-supplied primary keys from create-only save paths. Affected components: * CollectionsController::edit() * EventDelegationsController::delegateEvent() * ShadowAttributesController::edit() * TagCollectionsController::edit()915 * TagCollectionsController::editWithTags() Attack requirements: The attacker must be authenticated and able to reach the affected MISP endpoints. No user interaction is required.
CVE-2026-54362 WRITEUP MEDIUM WRITEUP
MISP template builder exposes non-visible custom galaxies across organisations
An incorrect visibility condition in the MISP event template builder allowed authenticated non-site-admin users to view galaxies that should not have been visible to their organisation. The custom access-control condition intended to restrict galaxies to those owned by the user’s organisation or distributed beyond it used a PHP comparison expression instead of a query condition. As a result, enabled galaxies, including organisation-only custom galaxies belonging to other organisations, could be exposed in the template builder galaxy list. This could disclose metadata about private galaxy definitions to unauthorised users.
CVE-2026-54393 WRITEUP MEDIUM WRITEUP
MISP Overmind theme stored XSS via unvalidated homepage setting
A stored cross-site scripting vulnerability exists in MISP when the Overmind theme is used. The setHomePage endpoint previously saved the user-controlled path value through setSettingInternal(), bypassing the normal setSetting() validation logic, including validate_homepage, which requires homepage paths to start with /. As a result, an authenticated user could store an arbitrary homepage value, including an XSS payload. The stored value was later rendered in app/View/News/index.ctp as the href attribute of the “Continue to homepage” link without HTML escaping. This could allow execution of attacker-controlled JavaScript in the browser context of the affected MISP instance when the crafted homepage link is rendered and interacted with. The issue is fixed by always persisting the homepage setting through setSetting(), ensuring validation and access checks are applied, and by HTML-escaping the homepage value before rendering it in the news view.
CVE-2026-54394 WRITEUP MEDIUM WRITEUP
MISP organisation logo path traversal allows retrieval of arbitrary PNG/SVG files
MISP contains a path traversal vulnerability in OrganisationsController::getOrgLogo. The vulnerable code builds organisation logo file paths using organisation-controlled fields such as id, name, and uuid without ensuring that the resolved file remains inside the intended APP/files/img/orgs/ directory. An attacker able to influence an organisation field, for example the organisation name, could use path traversal sequences to cause MISP to return arbitrary readable .png or .svg files from outside the organisation logo directory. The issue is fixed by resolving candidate paths with realpath() and verifying that they remain under the expected base directory before serving the file.
CVE-2026-54395 WRITEUP MEDIUM WRITEUP
MISP UiBeta event index reflected XSS in advanced filter popup
MISP contains a reflected cross-site scripting vulnerability in the UiBeta event index view. The urlparams value is inserted into an inline JavaScript handler using HTML escaping inside a single-quoted JavaScript string. Because browsers HTML-decode attribute values before JavaScript parsing, a crafted searcheventinfo value can restore encoded quote characters and break out of the JavaScript string. An attacker could craft a malicious URL that, when opened by a victim using the UiBeta event index, executes arbitrary JavaScript in the victim’s browser in the context of the MISP instance. The issue is fixed by encoding the value as a JavaScript string literal with json_encode() before applying HTML escaping at the attribute layer.
CVE-2026-54396 WRITEUP MEDIUM WRITEUP
MISP AuthKey edit endpoint allows authenticated user email enumeration
An information disclosure vulnerability exists in the MISP AuthKey edit functionality. When a validation error occurs during an AuthKey edit request, the user dropdown was populated using the attacker-controlled AuthKey.user_id value from the submitted request data. An authenticated user with permission to edit an AuthKey could submit arbitrary user IDs and observe the returned dropdown data, allowing enumeration of user email addresses. The issue is fixed by deriving the dropdown user from the persisted AuthKey owner instead of the request body.
CVE-2026-54397 WRITEUP MEDIUM WRITEUP
MISP event editing allows unauthorized assignment to undisclosed sharing groups
A vulnerability in MISP’s non-REST event editing path allowed an authenticated user with event edit permissions to manipulate the submitted form data and set an event’s sharing_group_id to a sharing group they were not authorized to use. When distribution was set to sharing group distribution, the non-REST save path accepted the submitted sharing_group_id without performing the same sharing group authorization check enforced by the REST edit path. An attacker could exploit this by tampering with the event edit request and assigning an event to an undisclosed or unauthorized sharing group. This could result in unauthorized use of restricted sharing groups, disclosure of the sharing group name in event listings, and unintended modification of the event’s distribution metadata. The issue is fixed by validating that the selected sharing group can be used by the current user when the sharing group is changed, and by clearing sharing_group_id when the event distribution is not set to sharing group distribution.
CVE-2026-54398 WRITEUP MEDIUM WRITEUP
MISP object edit authorization bypass allows unauthorized sharing group assignment
An authorization flaw in MISP’s object add/edit handling allowed an authenticated user with object editing permissions to assign a MISP object, or attributes contained within an object, to a sharing group that the user was not authorized to use or view. When editing objects, the sharing group validation was performed against the wrong request data structure after object fields had been merged to the top level, causing the check to be bypassed. In addition, attributes embedded in objects were not individually validated for authorized sharing group use. An attacker could craft a request with distribution set to 4 and an arbitrary sharing_group_id, potentially disclosing the existence or name of otherwise non-visible sharing groups and improperly modifying the distribution metadata of objects or contained attributes.
CVE-2026-53901 WRITEUP HIGH WRITEUP
Cerebrate before v1.37 allows mass assignment of record identifiers during object creation
Cerebrate before version 1.37 contains a mass-assignment vulnerability in the generic CRUD add path. The add() handler attempted to remove an attacker-supplied id from $params before normalizing the request through __massageInput(). Because the normalized $input could still contain an id field, a user able to reach an affected add endpoint could supply an identifier that should have been server-controlled. Successful exploitation could allow creation of objects with attacker-chosen identifiers, potentially causing unauthorized data manipulation, object spoofing, inconsistent references, or disruption through identifier collisions, depending on the affected model and endpoint permissions. The issue was fixed in v1.37 by removing id from the normalized input before entity patching.
CVE-2026-53911 WRITEUP MEDIUM WRITEUP
Cerebrate < 1.37 - Authenticated Mass Assignment Record Overwrite
Cerebrate before version 1.37 allowed the id primary key field to be supplied through request input during CRUD edit operations and certain custom entity patching flows. In affected entities that did not explicitly mark id as inaccessible, an authenticated attacker could submit a crafted edit request containing the id of another record, causing the save operation to update that unrelated record instead of the record identified by the route parameter. The issue affected several entity types inheriting permissive mass-assignment defaults, including User, Role, UserSetting, LocalTool, PermissionLimitation, and EnumerationCollection. Since UserSettings edit functionality was reachable by any authenticated user, exploitation could allow unauthorized modification of records within the same entity type, with impact depending on the affected endpoint and writable fields. Cerebrate 1.37 fixes this by stripping id from request input after marshalling callbacks and by globally marking id as inaccessible in the base AppModel entity. The discovery of those potential vulnerabilities are inherited from initial finding from Jeroen Pinoy additional support from AI-Assisted Optus 4.8 (the commit wrongly assign Claude Fable 5 as the model switched) and coordinated by Andras Iklody.
CVE-2026-10854 WRITEUP MEDIUM WRITEUP
Unauthorized exposure of private galaxies in MISP event template creation
A visibility control issue in the event template creation workflow allowed non-site-admin users to access private galaxies belonging to other organisations. The event template builder loaded all enabled galaxies without applying organisation or distribution-based access restrictions, potentially exposing private galaxy metadata such as galaxy type and description to users who should not have visibility. The issue has been fixed by restricting galaxy queries for non-site-admin users to galaxies owned by the user’s organisation or galaxies with a non-private distribution setting. Site administrators retain visibility of all enabled galaxies.
CVSS 4.3
CVE-2026-10855 WRITEUP MEDIUM WRITEUP
MISP Event template importer authorization bypass
An authorization flaw existed in the MISP Event Template Importer overwrite workflow. When importing an event template in overwrite mode, the application checked whether a matching template already existed but did not verify that the importing user belonged to the organization that owned the existing template. As a result, an authenticated user with access to the template import functionality could forcibly overwrite an event template owned by another organization. Successful exploitation could allow unauthorized modification of another organization’s event template, potentially altering template structure, attributes, or metadata used for subsequent event creation or sharing workflows. Site administrators are not affected by this restriction, as they are explicitly allowed to overwrite templates across organizations. The issue was fixed by enforcing an ownership check before overwrite: non-site-admin users may only overwrite templates owned by their own organization.
CVSS 4.3
CVE-2026-10856 WRITEUP MEDIUM WRITEUP
Open redirect in MISP dashboard button widget URL handling
A URL validation flaw in the MISP dashboard button widget allowed a crafted relative-looking URL to be accepted as a local path while being interpreted by browsers as an external URL. The validation rejected URLs containing an explicit scheme, host, or user component, but did not reject paths beginning with a slash followed by a backslash, such as /\example.com. Some browsers normalize backslashes in URLs as forward slashes, which can turn this into a scheme-relative external navigation target. In addition, the generated href concatenated the reconstructed URL with the original URL, increasing the possibility of unsafe or malformed link generation. An attacker able to configure or influence a dashboard button URL could craft a button that appears to point inside the application but redirects users to an attacker-controlled site when clicked. This could be used for phishing, credential theft, or social engineering. The patch fixes the issue by rejecting empty paths and paths starting with /\, and by emitting only the reconstructed validated URL in the anchor href.
CVSS 6.1
CVE-2026-10860 WRITEUP MEDIUM WRITEUP
MISP CRUDComponent delete validation bypass via operator precedence error
A logic error in the MISP CRUD component delete handler allowed validation failures to be bypassed when requests used the HTTP DELETE method. Due to missing parentheses in the delete condition, the expression was evaluated as ($validationError === null && POST) || DELETE, meaning a DELETE request could proceed even when the delete validation callback had rejected the operation. An authenticated attacker with access to an affected delete endpoint could abuse this flaw to delete records that should have been protected by application-level validation or authorization checks.
CVSS 6.5
CVE-2026-10861 WRITEUP MEDIUM WRITEUP
MISP post-login open redirect via pre_login_requested_url
An open redirect vulnerability existed in MISP UsersController::routeafterlogin() because the value stored in the pre_login_requested_url session key was used as the post-login redirect destination without sufficiently enforcing that it was a local application path. An unauthenticated remote attacker could craft a link that causes a victim to visit a trusted MISP instance and, after successful authentication, be redirected to an attacker-controlled external URL. This could be abused to increase the credibility of phishing attacks, redirect users to counterfeit login pages, or deliver attacker-controlled content from an untrusted domain. CWE-601 describes this weakness as accepting user-controlled input that specifies an external link and using it in a redirect, with phishing as a common consequence. The patch mitigates the issue by decoding and parsing the URL, rejecting URLs with a scheme, host, user component, missing or non-local path, and protocol-relative forms such as //example.com and /\example.com.
CVSS 6.1
CVE-2026-10863 WRITEUP HIGH WRITEUP
MISP User-controlled order parameter in correlations over-correlation endpoint
A security issue was fixed in the correlations over-correlation endpoint where the order query parameter was accepted from user-controlled named request parameters. This allowed an authenticated user to override the server-defined ordering of over-correlating values. Depending on how the value was processed by the underlying data access layer, this could allow manipulation of database query ordering and potentially expose the application to unsafe query construction. The patch removes order from the set of request-controlled parameters and instead sets the ordering server-side to occurrence desc after processing allowed user parameters. Affected component: app/Controller/CorrelationsController.php, overCorrelations() Security impact: An authenticated attacker could influence the ordering clause used by the over-correlations query. The direct impact appears limited to query manipulation unless further evidence confirms SQL injection or unauthorized data exposure through the manipulated ordering expression.
CVSS 8.1
CVE-2026-10864 WRITEUP MEDIUM WRITEUP
MISP Dashboard widget field selection may expose restricted user and organisation data
A vulnerability in the MISP dashboard widgets allowed an authenticated user to manipulate the fields option and influence which fields were returned by the New Users and New Organisations widgets. In some cases, requesting a field set that became empty after validation or redaction could cause the underlying query to fall back to returning unintended model fields. For the New Users widget, this could allow a non-site-admin user to obtain user e-mail addresses even when user e-mail disclosure was disabled by configuration. For the New Organisations widget, crafted field selection could similarly result in unintended organisation fields being included in the dashboard response. The issue was caused by applying field filtering and redaction in a way that could leave the selected field list empty. The patch ensures that the allowed field list is built safely, that restricted fields such as user e-mail addresses are removed before user-supplied field selection is processed, and that an empty field selection falls back only to the permitted default fields. Impact: An authenticated low-privileged user with access to the affected dashboard widgets may be able to disclose restricted user or organisation metadata, including user e-mail addresses depending on configuration.
CVSS 4.3
CVE-2026-10868 WRITEUP CRITICAL WRITEUP
MISP user edit endpoint mass assignment vulnerability allows unauthorized user account modification
A mass assignment vulnerability exists in the MISP user edit functionality due to insufficient filtering of user-supplied fields in UsersController::edit(). When processing edit requests, the application accepted a user-controlled User.id value from request data. An authenticated attacker could craft a modified request containing another user identifier, potentially causing updates to be applied to an unintended user account. Depending on the editable fields and the attacker’s privileges, this could allow unauthorized modification of user account attributes and impact account integrity. The issue was addressed by explicitly removing the User.id field from request data before processing the user edit operation.
CVE-2026-44379 WRITEUP MEDIUM WRITEUP
MISP: Improper UUID validation in MISP Collections
MISP is an open source threat intelligence and sharing platform. Prior to 2.5.37, MISP Collections did not enforce RFC 4122 UUID validation on the uuid field. As a result, a user able to create or modify Collection records could submit malformed UUID values, potentially causing integrity issues or unexpected behaviour in code paths that assume Collection UUIDs are valid identifiers. This vulnerability is fixed in 2.5.37.
CVSS 5.3
CVE-2017-7215 WRITEUP MEDIUM WRITEUP
MISP < 2.4.68 - Cross-Site Scripting in Index Filter Tool and Organisation Landing Page
Cross site scripting in some view elements in the index filter tool in app/webroot/js/misp2.4.68.js and the organisation landing page in app/View/Organisations/ajax/landingpage.ctp of MISP before 2.4.69 allows remote attackers to inject arbitrary web script or HTML.
CVSS 6.1
CVE-2018-19908 WRITEUP HIGH WRITEUP
MISP 2.4.90-2.4.98 - Authenticated OS Command Injection via STIX Import Filename
An issue was discovered in MISP 2.4.9x before 2.4.99. In app/Model/Event.php (the STIX 1 import code), an unescaped filename string is used to construct a shell command. This vulnerability can be abused by a malicious authenticated user to execute arbitrary commands by tweaking the original filename of the STIX import.
