## What is CVE-2025-32944?

CVE-2025-32944 is a medium-severity denial of service vulnerability in framasoft:peertube, published on 15 Apr 2025. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

The vulnerability allows any authenticated user to cause the PeerTube server to stop functioning in a persistent manner.  If user import is enabled (which is the default setting), any registered user can upload an archive for importing. The code uses the yauzl library for reading the archive. If the yauzl library encounters a filename that is considered illegal, it raises an exception that is uncaught by PeerTube, leading to a crash which repeats infinitely on startup.

Weakness: CWE-248 (Uncaught Exception)

What it is: CVE-2025-32944 is a medium-severity denial of service vulnerability in framasoft:peertube, published on 15 Apr 2025. Any signed-in user can exploit it over the network, with no action from the victim.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2025-32944 exists.

Affected product: framasoft:peertube. 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.
