CVE-2026-41454 WRITEUP HIGH WRITEUP
WeKan < 8.35 Missing Authorization via Integration REST API
WeKan before 8.35 contains a missing authorization vulnerability in the Integration REST API endpoints that allows authenticated board members to perform administrative actions without proper privilege verification. Attackers can enumerate integrations including webhook URLs, create new integrations, modify or delete existing integrations, and manage integration activities by exploiting insufficient authorization checks in the JsonRoutes REST handlers.
CVSS 8.3
CVE-2026-41455 WRITEUP HIGH WRITEUP
WeKan < 8.35 SSRF via Webhook URL
WeKan before 8.35 contains a server-side request forgery vulnerability in webhook integration URL handling where the URL scheme field accepts any string without protocol restriction or destination validation. Attackers who can create or modify integrations can set webhook URLs to internal network addresses, causing the server to issue HTTP POST requests to attacker-controlled internal targets with full board event payloads, and can additionally exploit response handling to overwrite arbitrary comment text without authorization checks.
CVSS 8.5
CVE-2026-30843 WRITEUP MEDIUM WRITEUP
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.
CVSS 6.5
CVE-2026-30844 WRITEUP HIGH WRITEUP
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.
CVSS 8.1
CVE-2026-30845 WRITEUP HIGH WRITEUP
Wekan 8.31.0-8.33 - Info Disclosure
Wekan is an open source kanban tool built with Meteor. In versions 8.31.0 through 8.33, the board composite publication in Wekan publishes all integration data for a board without any field filtering, exposing sensitive fields including webhook URLs and authentication tokens to any subscriber. Since board publications are accessible to all board members regardless of their role (including read-only and comment-only users), and even to unauthenticated DDP clients for public boards, any user who can access a board can retrieve its webhook credentials. This token leak allows attackers to make unauthenticated requests to the exposed webhooks, potentially triggering unauthorized actions in connected external services. This issue has been fixed in version 8.34.
CVSS 8.2
CVE-2026-30846 WRITEUP HIGH WRITEUP
Wekan 8.31.0-8.33 - Info Disclosure
Wekan is an open source kanban tool built with Meteor. In versions 8.31.0 through 8.33, the globalwebhooks publication exposes all global webhook integrations—including sensitive url and token fields—without performing any authentication check on the server side. Although the subscription is normally invoked from the admin settings page, the server-side publication has no access control, meaning any DDP client, including unauthenticated ones, can subscribe and receive the data. This allows an unauthenticated attacker to retrieve global webhook URLs and authentication tokens, potentially enabling unauthorized use of those webhooks and access to connected external services. This issue has been fixed in version 8.34.
CVSS 7.5
CVE-2026-30847 WRITEUP MEDIUM WRITEUP
Wekan 8.31.0-8.33 - Info Disclosure
Wekan is an open source kanban tool built with Meteor. In versions 8.31.0 through 8.33, the notificationUsers publication in Wekan publishes user documents with no field filtering, causing the ReactiveCache.getUsers() call to return all fields including highly sensitive data such as bcrypt password hashes, active session login tokens, email verification tokens, full email addresses, and any stored OAuth tokens. Unlike Meteor's default auto-publication which strips the services field for security, custom publications return whatever fields the cursor contains, meaning all subscribers receive the complete user documents. Any authenticated user who triggers this publication can harvest credentials and active session tokens for other users, enabling password cracking, session hijacking, and full account takeover. This issue has been fixed in version 8.34.
CVSS 6.5
CVE-2026-25560 WRITEUP CRITICAL WRITEUP
WeKan < 8.19 - LDAP Injection in Authentication Filter
WeKan versions prior to 8.19 contain an LDAP filter injection vulnerability in LDAP authentication. User-supplied username input is incorporated into LDAP search filters and DN-related values without adequate escaping, allowing an attacker to manipulate LDAP queries during authentication.
CVSS 9.8
CVE-2026-25561 WRITEUP HIGH WRITEUP
WeKan < 8.19 - Incorrect Authorization in Attachment Upload API
WeKan versions prior to 8.19 contain an authorization weakness in the attachment upload API. The API does not fully validate that provided identifiers (such as boardId, cardId, swimlaneId, and listId) are consistent and refer to a coherent card/board relationship, enabling attempts to upload attachments with mismatched object relationships.
CVSS 7.5
CVE-2026-25562 WRITEUP MEDIUM WRITEUP
WeKan < 8.19 - Unauthorized Attachment Metadata Exposure via Attachments Publication
WeKan versions prior to 8.19 contain an information disclosure vulnerability in the attachments publication. Attachment metadata can be returned without properly scoping results to boards and cards accessible to the requesting user, potentially exposing attachment metadata to unauthorized users.
