CVE-2025-56643
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedRequarks Wiki.js 2.5.307 does not properly revoke or invalidate active JWT tokens when a user logs out. As a result, previously issued tokens remain valid and can be reused to access the system, even after logout. This behavior affects session integrity and may allow unauthorized access if a token is compromised. The issue is present in the authentication resolver logic and affects both the GraphQL endpoint and the logout mechanism.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceWiki.js 2.5.307 fails to revoke or invalidate active JWT tokens upon user logout. The authentication resolver logic does not implement proper token invalidation, allowing previously issued tokens to remain valid indefinitely even after the user has logged out. This enables session hijacking and unauthorized access if a token is intercepted or leaked.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check installed Wiki.js versionRun `node -e "console.log(require('./package.json').version)"` in the Wiki.js installation directory, or check the version displayed in the admin panel under System Info.Affected if The installed version is exactly 2.5.307.
-
Verify JWT is used for authenticationCheck the authentication configuration in the Wiki.js admin panel or inspect the config.yml file for auth strategies that issue JWT tokens (such as local, LDAP, or OAuth).Affected if JWT-based authentication is enabled and active.
-
Test token invalidation after logoutLog in with a user account, capture the JWT token from browser storage or API response, then log out. Attempt to use the same token in an API request (e.g., `curl -H "Authorization: Bearer <token>" <wiki-url>/api/`).Affected if The token remains valid and grants access after logout (token is NOT invalidated).
-
Inspect authentication resolver codeExamine the source file handling the logout endpoint and authentication resolution (typically in the `server/modules/auth/` directory). Look for any token blacklist, revocation list, or database query that invalidates the token on logout.Affected if No token invalidation or blacklist mechanism exists in the logout flow.
You are affected if you run Wiki.js version 2.5.307 and find that JWT tokens remain functional after a user logs out, indicating missing token revocation logic.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement server-side token blacklisting or revocation mechanism in the logout flow and authentication resolver to invalidate active JWT tokens upon logout. Consider adding short expiration times and implementing token refresh rotation.
