## What is CVE-2025-65883?

CVE-2025-65883 is a high-severity authentication bypass vulnerability in n/a, published on 4 Dec 2025. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

A vulnerability has been identified in Genexis Platinum P4410 router (Firmware P4410-V2–1.41) that allows a local network attacker to achieve Remote Code Execution (RCE) with root privileges. The issue occurs due to improper session invalidation after administrator logout. When an administrator logs out, the session token remains valid. An attacker on the local network can reuse this stale token to send crafted requests via the router’s diagnostic endpoint, resulting in command execution as root.

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

Check this codebase for CVE-2025-65883 and fix it if it is affected.

What it is: CVE-2025-65883 is a high-severity authentication bypass vulnerability in n/a, published on 4 Dec 2025. It can only be exploited from the same machine or local network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2025-65883 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.
