CVSS 7.5
CVE-2026-30830 WRITEUP MEDIUM
defuddle < 0.9.0 - Cross-Site Scripting via Image Alt Attribute
Defuddle cleans up HTML pages. Prior to version 0.9.0, the _findContentBySchemaText method in src/defuddle.ts interpolates image src and alt attributes directly into an HTML string without escaping. An attacker can use a " in the alt attribute to break out of the attribute context and inject event handler. This issue has been patched in version 0.9.0.
CVSS 6.1
CVE-2026-30839 WRITEUP MEDIUM
wallos < 4.6.2 - Server-Side Request Forgery via testwebhooknotifications.php
Wallos is an open-source, self-hostable personal subscription tracker. Prior to version 4.6.2, testwebhooknotifications.php does not validate the target URL against private/reserved IP ranges, enabling full-read SSRF. The server response is returned to the caller. This issue has been patched in version 4.6.2.
CVSS 4.3
CVE-2026-30840 WRITEUP HIGH
wallos < 4.6.2 - Server-Side Request Forgery via Notification Tester

CVE-2026-30841 WRITEUP MEDIUM
wallos < 4.6.2 - Reflected Cross-Site Scripting via Password Reset Token and Email Parameters
Wallos is an open-source, self-hostable personal subscription tracker. Prior to version 4.6.2, passwordreset.php outputs $_GET["token"] and $_GET["email"] directly into HTML input value attributes using <?= $token ?> and <?= $email ?> without calling htmlspecialchars(). This allows reflected XSS by breaking out of the attribute context. This issue has been patched in version 4.6.2.
CVSS 6.1
CVE-2026-30842 WRITEUP MEDIUM
Wallos <4.6.2 - Privilege Escalation
Wallos is an open-source, self-hostable personal subscription tracker. Prior to version 4.6.2, Wallos allows an authenticated user to delete avatar files uploaded by other users. The avatar deletion endpoint does not verify that the requested avatar belongs to the current user. As a result, any authenticated user who knows or can discover another user's uploaded avatar filename can delete that file. This issue has been patched in version 4.6.2.
CVSS 4.3
CVE-2026-2721 WRITEUP MEDIUM
MailArchiver <= 4.4.0 - Authenticated Stored Cross-Site Scripting via Admin Settings
The MailArchiver plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in all versions up to, and including, 4.4.0 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.
CVSS 4.8
CVE-2025-70363 WRITEUP HIGH
Ibexa & Ciril GROUP eZ Platform / Ciril Platform 2.x - Unauthenticated Sensitive Data Exposure via REST API

CVE-2026-28514 WRITEUP CRITICAL
Rocket.Chat < 7.8.6, 7.9.8, 7.10.7, 7.11.4, 7.12.4, 7.13.3, 8.0.0 - Authentication Bypass
Rocket.Chat is an open-source, secure, fully customizable communications platform. Prior to versions 7.8.6, 7.9.8, 7.10.7, 7.11.4, 7.12.4, 7.13.3, and 8.0.0, a critical authentication bypass vulnerability exists in Rocket.Chat's account service used in the ddp-streamer micro service that allows an attacker to log in to the service as any user with a password set, using any arbitrary password. The vulnerability stems from a missing await keyword when calling an asynchronous password validation function, causing a Promise object (which is always truthy) to be evaluated instead of the actual boolean validation result. This may lead to account takeover of any user whose username is known or guessable. This issue has been patched in versions 7.8.6, 7.9.8, 7.10.7, 7.11.4, 7.12.4, 7.13.3, and 8.0.0.
CVSS 9.8
CVE-2026-29075 WRITEUP HIGH
mesa < 3.5.0 - Remote Code Execution via benchmarks.yml Workflow
Mesa is an open-source Python library for agent-based modeling, simulating complex systems and exploring emergent behaviors. In version 3.5.0 and prior, checking out of untrusted code in benchmarks.yml workflow may lead to code execution in privileged runner. This issue has been patched via commit c35b8cd.
CVSS 8.3
CVE-2026-29087 WRITEUP HIGH
@hono/node-server <1.19.10 - Auth Bypass
@hono/node-server allows running the Hono application on Node.js. Prior to version 1.19.10, when using @hono/node-server's static file serving together with route-based middleware protections (e.g. protecting /admin/*), inconsistent URL decoding can allow protected static resources to be accessed without authorization. In particular, paths containing encoded slashes (%2F) may be evaluated differently by routing/middleware matching versus static file path resolution, enabling a bypass where middleware does not run but the static file is still served. This issue has been patched in version 1.19.10.
CVSS 7.5
CVE-2026-29089 WRITEUP HIGH
TimescaleDB 2.23.0-2.25.1 - Code Injection
TimescaleDB is a time-series database for high-performance real-time analytics packaged as a Postgres extension. From version 2.23.0 to 2.25.1, PostgreSQL uses the search_path setting to locate unqualified database objects (tables, functions, operators). If the search_path includes user-writable schemas a malicious user can create functions in that schema that shadow builtin postgres functions and will be called instead of the postgres functions leading to arbitrary code execution during extension upgrade. This issue has been patched in version 2.25.2.
CVSS 8.8
CVE-2026-29091 WRITEUP HIGH
locutus < 3.0.0 - Remote Code Execution via call_user_func_array Eval Injection
Locutus brings stdlibs of other programming languages to JavaScript for educational purposes. Prior to version 3.0.0, a remote code execution (RCE) flaw was discovered in the locutus project, specifically within the call_user_func_array function implementation. The vulnerability allows an attacker to inject arbitrary JavaScript code into the application's runtime environment. This issue stems from an insecure implementation of the call_user_func_array function (and its wrapper call_user_func), which fails to properly validate all components of a callback array before passing them to eval(). This issue has been patched in version 3.0.0.
CVSS 8.1
CVE-2026-29178 WRITEUP HIGH
Lemmy < 0.19.16 - Unauthenticated Server-Side Request Forgery via Image Endpoint File Type Parameter
Lemmy, a link aggregator and forum for the fediverse, is vulnerable to server-side request forgery via a dependency on activitypub_federation, a framework for ActivityPub federation in Rust. Prior to version 0.19.16, the GET /api/v4/image/{filename} endpoint is vulnerable to unauthenticated SSRF through parameter injection in the file_type query parameter. An attacker can inject arbitrary query parameters into the internal request to pict-rs, including the proxy parameter which causes pict-rs to fetch arbitrary URLs. This issue has been patched in version 0.19.16.
CVE-2026-29789 WRITEUP CRITICAL
Vito <3.20.3 - Privilege Escalation
Vito is a self-hosted web application that helps manage servers and deploy PHP applications into production servers. Prior to version 3.20.3, a missing authorization check in workflow site-creation actions allows an authenticated attacker with workflow write access in one project to create/manage sites on servers belonging to other projects by supplying a foreign server_id. This issue has been patched in version 3.20.3.
CVSS 9.9
CVE-2026-29790 WRITEUP MEDIUM
dbt-common <1.34.2/1.37.3 - Path Traversal
dbt-common is the shared common utilities for dbt-core and adapter implementations use. Prior to versions 1.34.2 and 1.37.3, a path traversal vulnerability exists in dbt-common's safe_extract() function used when extracting tarball archives. The function uses os.path.commonprefix() to validate that extracted files remain within the intended destination directory. However, commonprefix() compares paths character-by-character rather than by path components, allowing a malicious tarball to write files to sibling directories with matching name prefixes. This issue has been patched in versions 1.34.2 and 1.37.3.
CVSS 5.3
CVE-2026-29795 WRITEUP MEDIUM
stellar-xdr <25.0.1 - Memory Corruption
stellar-xdr is a library and CLI containing types and functionality for working with Stellar XDR. Prior to version 25.0.1, StringM::from_str does not validate that the input length is within the declared maximum (MAX). Calling StringM::<N>::from_str(s) where s is longer than N bytes succeeds and returns an Ok value instead of Err(Error::LengthExceedsMax), producing a StringM that violates its length invariant. This affects any code that constructs StringM values from string input using FromStr (including str::parse), and relies on the type's maximum length constraint being enforced. An oversized StringM could propagate through serialization, validation, or other logic that assumes the invariant holds. This issue has been patched in version 25.0.1.
CVSS 4.0
CVE-2026-30223 WRITEUP HIGH
olivetin < 3000.11.1 - Insufficient JWT Audience Verification
OliveTin gives access to predefined shell commands from a web interface. Prior to version 3000.11.1, when JWT authentication is configured using either "authJwtPubKeyPath" (local RSA public key) or "authJwtHmacSecret" (HMAC secret), the configured audience value (authJwtAud) is not enforced during token parsing. As a result, validly signed JWT tokens with an incorrect aud claim are accepted for authentication. This allows authentication using tokens intended for a different audience/service. This issue has been patched in version 3000.11.1.
CVSS 8.8
CVE-2026-30224 WRITEUP MEDIUM
olivetin < 3000.11.1 - Session Fixation via Incomplete Logout
OliveTin gives access to predefined shell commands from a web interface. Prior to version 3000.11.1, OliveTin does not revoke server-side sessions when a user logs out. Although the browser cookie is cleared, the corresponding session remains valid in server storage until expiry (default ≈ 1 year). An attacker with a previously stolen or captured session cookie can continue authenticating after logout, resulting in a post-logout authentication bypass. This is a session management flaw that violates expected logout semantics. This issue has been patched in version 3000.11.1.
CVSS 5.4
CVE-2026-30225 WRITEUP MEDIUM
OliveTin <3000.11.1 - Privilege Escalation
OliveTin gives access to predefined shell commands from a web interface. Prior to version 3000.11.1, an authentication context confusion vulnerability in RestartAction allows a low‑privileged authenticated user to execute actions they are not permitted to run. RestartAction constructs a new internal connect.Request without preserving the original caller’s authentication headers or cookies. When this synthetic request is passed to StartAction, the authentication resolver falls back to the guest user. If the guest account has broader permissions than the authenticated caller, this results in privilege escalation and unauthorized command execution. This vulnerability allows a low‑privileged authenticated user to bypass ACL restrictions and execute arbitrary configured shell actions. This issue has been patched in version 3000.11.1.
CVSS 5.3
CVE-2026-30233 WRITEUP MEDIUM
olivetin < 3000.11.1 - Authenticated Information Disclosure via Dashboard and API Endpoints
OliveTin gives access to predefined shell commands from a web interface. Prior to version 3000.11.1, an authorization flaw in OliveTin allows authenticated users with view: false permission to enumerate action bindings and metadata via dashboard and API endpoints. Although execution (exec) may be correctly denied, the backend does not enforce IsAllowedView() when constructing dashboard and action binding responses. As a result, restricted users can retrieve action titles, IDs, icons, and argument metadata. This issue has been patched in version 3000.11.1.
CVSS 6.5
CVE-2026-30241 WRITEUP HIGH
mercurius < 16.8.0 - Incorrect Authorization via WebSocket Subscription Query Depth Bypass
Mercurius is a GraphQL adapter for Fastify. Prior to version 16.8.0, Mercurius fails to enforce the configured queryDepth limit on GraphQL subscription queries received over WebSocket connections. The depth check is correctly applied to HTTP queries and mutations, but subscription queries are parsed and executed without invoking the depth validation. This allows a remote client to submit arbitrarily deeply nested subscription queries over WebSocket, bypassing the intended depth restriction. On schemas with recursive types, this can lead to denial of service through exponential data resolution on each subscription event. This issue has been patched in version 16.8.0.
CVSS 8.2
CVE-2026-30843 WRITEUP MEDIUM
Wekan 8.32-8.33 - Authenticated Insecure Direct Object Reference in Custom Fields Endpoint
Wekan is an open source kanban tool built with Meteor. Versions 8.32 and 8.33 have a critical Insecure Direct Object Reference (IDOR) issue which could allow unauthorized users to modify custom fields across boards through its custom fields update endpoints, potentially leading to unauthorized data manipulation. The PUT /api/boards/:boardId/custom-fields/:customFieldId endpoint in Wekan validates that the authenticated user has access to the specified boardId, but the subsequent database update uses only the custom field's _id as a filter without confirming the field actually belongs to that board. This means an attacker who owns any board can modify custom fields on any other board by supplying a foreign custom field ID, and the same flaw exists in the POST, PUT, and DELETE endpoints for dropdown items under custom fields. The required custom field IDs can be obtained by exporting a board (which only needs read access), since the exported JSON includes the IDs of all board components. The authorization check is performed against the wrong resource, allowing cross-board custom field manipulation. This issue has been fixed in version 8.34.

CVE-2026-30844 WRITEUP HIGH
Wekan 8.32-8.33 - Authenticated Server-Side Request Forgery via Attachment URL Loading
Wekan is an open source kanban tool built with Meteor. Versions 8.32 and 8.33 are vulnerable to Server-Side Request Forgery (SSRF) via attachment URL loading. During board import in Wekan, attachment URLs from user-supplied JSON data are fetched directly by the server without any URL validation or filtering, affecting both the Wekan and Trello import flows. The parseActivities() and parseActions() methods extract user-controlled attachment URLs, which are then passed directly to Attachments.load() for download with no sanitization. This Server-Side Request Forgery (SSRF) vulnerability allows any authenticated user to make the server issue arbitrary HTTP requests, potentially accessing internal network services such as cloud instance metadata endpoints (exposing IAM credentials), internal databases, and admin panels that are otherwise unreachable from outside the network. This issue has been fixed in version 8.34.
