## What is CVE-2024-45261?

CVE-2024-45261 is a high-severity authentication bypass vulnerability in n/a, published on 24 Oct 2024. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

An issue was discovered on certain GL-iNet devices, including MT6000, MT3000, MT2500, AXT1800, and AX1800 4.6.2. The SID generated for a specific user is not tied to that user itself, which allows other users to potentially use it for authentication. Once an attacker bypasses the application's authentication procedures, they can generate a valid SID, escalate privileges, and gain full control.

Weakness: CWE-863 (Incorrect Authorization)

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2024-45261 and fix it if it is affected.

What it is: CVE-2024-45261 is a high-severity authentication bypass vulnerability in n/a, published on 24 Oct 2024. 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-2024-45261 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.
