## What is CVE-2026-39368?

CVE-2026-39368 is a medium-severity server-side request forgery vulnerability in Wwbn Avideo, published on 7 Apr 2026. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

WWBN AVideo is an open source video platform. In versions 26.0 and prior, the Live restream log callback flow accepted an attacker-controlled restreamerURL and later fetched that stored URL server-side, enabling stored SSRF for authenticated streamers. The vulnerable flow allowed a low-privilege user with streaming permission to store an arbitrary callback URL and trigger server-side requests to loopback or internal HTTP services through the restream log feature.

Weakness: CWE-918 (Server-Side Request Forgery)

- WWBN/AVideo (Packagist): affected all versions up to 26.0; no fix listed

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.
