## What is CVE-2025-56643?

CVE-2025-56643 is a critical vulnerability in n/a, published on 18 Nov 2025. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

Requarks 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.

Weakness: CWE-613 (DEPRECATED: Insufficient Session Expiration)

Check this codebase for CVE-2025-56643 and fix it if it is affected.

What it is: CVE-2025-56643 is a critical vulnerability in n/a, published on 18 Nov 2025. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2025-56643 in the wild and no public exploit code.

Affected product: n/a. No package-level version data is available, so check the vendor advisory linked from the reference page.

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
