CVE-2025-56643Network attack vector

Post-logout account access via reusable JWTs

Published Nov 18, 2025 · Updated Nov 19, 2025

Insufficient session expiration in Requarks Wiki.js 2.5.307 allows remote attackers to reuse a compromised JWT after its user logs out. The authentication resolver's logout path fails to revoke or invalidate the issued JWT, so the GraphQL endpoint continues accepting it. Exploitation requires possession of a user's token and preserves only the authenticated actions that token already authorizes.
