## What is GHSA-23q2-5gf8-gjpp?

GHSA-23q2-5gf8-gjpp is an authentication bypass vulnerability in uptime-kuma, published on 19 Apr 2024. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

### Summary
This is basically [GHSA-88j4-pcx8-q4q](https://github.com/louislam/uptime-kuma/security/advisories/GHSA-88j4-pcx8-q4q3) but instead of changing passwords, when enabling authentication.

### PoC
- Open Uptime Kuma with authentication disabled
- Enable authentication using another window
- Access the platform using the previously logged-in window
- Note that access (read-write) remains despite the enabled authentication
- Expected behaviour:
  - After enabling authentication, all previously connected sessions should be invalidated, requiring users to log in.
- Actual behaviour:
  - The system retains sessions and never logs out users unless explicitly done by clicking logout or refreshing the page.

### Impact
See [GHSA-g9v2-wqcj-j99g](https://github.com/louislam/uptime-kuma/security/advisories/GHSA-g9v2-wqcj-j99g) and [GHSA-88j4-pcx8-q4q](https://github.com/louislam/uptime-kuma/security/advisories/GHSA-88j4-pcx8-q4q3)

TBH this is quite a niche edge case, so I don't know if this even warrants a security report.

What it is: GHSA-23q2-5gf8-gjpp is an authentication bypass vulnerability in uptime-kuma, published on 19 Apr 2024. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: There is no known exploitation of GHSA-23q2-5gf8-gjpp in the wild and no public exploit code.

Affected packages and fixed versions:
- uptime-kuma (npm): affected all versions; fixed in 1.23.12
- uptime-kuma (npm): affected all versions; fixed in 1.23.12

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.
