## What is CVE-2024-29191?

CVE-2024-29191 is a medium-severity cross-site scripting vulnerability in AlexxIT go2rtc, published on 4 Apr 2024. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.

### Official description

gotortc is a camera streaming application. Versions 1.8.5 and prior are vulnerable to DOM-based cross-site scripting. The links page (`links.html`) appends the `src` GET parameter (`[0]`) in all of its links for 1-click previews. The context in which `src` is being appended is `innerHTML` (`[1]`), which will insert the text as HTML. Commit 3b3d5b033aac3a019af64f83dec84f70ed2c8aba contains a patch for the issue.

Weakness: CWE-79 (Improper Neutralization of Input During Web Page Generation)

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.
