CVE-2026-35594 WRITEUP MEDIUM
Vikunja Link Share JWT tokens remain valid for 72 hours after share deletion or permission downgrade
Vikunja is an open-source self-hosted task management platform. Prior to 2.3.0, Vikunja's link share authentication (GetLinkShareFromClaims in pkg/models/link_sharing.go) constructs authorization objects entirely from JWT claims without any server-side database validation. When a project owner deletes a link share or downgrades its permissions, all previously issued JWTs continue to grant the original permission level for up to 72 hours (the default service.jwtttl). This vulnerability is fixed in 2.3.0.
CVSS 6.5
CVE-2026-35595 WRITEUP HIGH
Vikunja Affected by Privilege Escalation via Project Reparenting
Vikunja is an open-source self-hosted task management platform. Prior to 2.3.0, the CanUpdate check at pkg/models/project_permissions.go:139-148 only requires CanWrite on the new parent project when changing parent_project_id. However, Vikunja's permission model uses a recursive CTE that walks up the project hierarchy to compute permissions. Moving a project under a different parent changes the permission inheritance chain. When a user has inherited Write access (from a parent project share) and reparents the child project under their own project tree, the CTE resolves their ownership of the new parent as Admin (permission level 2) on the moved project. This vulnerability is fixed in 2.3.0.
CVSS 8.3
CVE-2026-35596 WRITEUP MEDIUM
Vikunja has Broken Access Control on Label Read via SQL Operator Precedence Bug
Vikunja is an open-source self-hosted task management platform. Prior to 2.3.0, the hasAccessToLabel function contains a SQL operator precedence bug that allows any authenticated user to read any label that has at least one task association, regardless of project access. Label titles, descriptions, colors, and creator information are exposed. This vulnerability is fixed in 2.3.0.
CVSS 4.3
CVE-2026-35597 WRITEUP MEDIUM
Vikunja Affected by TOTP Brute-Force Due to Non-Functional Account Lockout
Vikunja is an open-source self-hosted task management platform. Prior to 2.3.0, the TOTP failed-attempt lockout mechanism is non-functional due to a database transaction handling bug. When a TOTP validation fails, the login handler in pkg/routes/api/v1/login.go calls HandleFailedTOTPAuth and then unconditionally rolls back. HandleFailedTOTPAuth in pkg/user/totp.go uses an in-memory counter (key-value store) to track failed attempts. When the counter reaches 10, it calls user.SetStatus(s, StatusAccountLocked) on the same database session s. Because the login handler always rolls back after a TOTP failure, the StatusAccountLocked write is undone. The in-memory counter correctly increments past 10, so the lockout code executes on every subsequent attempt, but the database write is rolled back every time. This allows unlimited brute-force attempts against TOTP codes. This vulnerability is fixed in 2.3.0.
CVSS 5.9
CVE-2026-35598 WRITEUP MEDIUM
Vikunja has Missing Authorization on CalDAV Task Read
Vikunja is an open-source self-hosted task management platform. Prior to 2.3.0, the CalDAV GetResource and GetResourcesByList methods fetch tasks by UID from the database without verifying that the authenticated user has access to the task's project. Any authenticated CalDAV user who knows (or guesses) a task UID can read the full task data from any project on the instance. This vulnerability is fixed in 2.3.0.
CVSS 4.3
CVE-2026-35599 WRITEUP MEDIUM
Vikunja has an Algorithmic Complexity DoS in Repeating Task Handler
Vikunja is an open-source self-hosted task management platform. Prior to 2.3.0, the addRepeatIntervalToTime function uses an O(n) loop that advances a date by the task's RepeatAfter duration until it exceeds the current time. By creating a repeating task with a 1-second interval and a due date far in the past, an attacker triggers billions of loop iterations, consuming CPU and holding a database connection for minutes per request. This vulnerability is fixed in 2.3.0.
CVSS 6.5
CVE-2026-35600 WRITEUP MEDIUM
Vikunja has HTML Injection via Task Titles in Overdue Email Notifications
Vikunja is an open-source self-hosted task management platform. Prior to 2.3.0, task titles are embedded directly into Markdown link syntax in overdue email notifications without escaping Markdown special characters. When rendered by goldmark and sanitized by bluemonday (which allows <a> and <img> tags), injected Markdown constructs produce phishing links and tracking pixels in legitimate notification emails. This vulnerability is fixed in 2.3.0.
CVSS 5.4
CVE-2026-35619 WRITEUP MEDIUM
OpenClaw < 2026.3.24 - Authorization Bypass via HTTP /v1/models Endpoint
OpenClaw before 2026.3.24 contains an authorization bypass vulnerability in the HTTP /v1/models endpoint that fails to enforce operator read scope requirements.
