## What is CVE-2024-39926?

CVE-2024-39926 is a medium-severity cross-site scripting vulnerability in n/a, published on 13 Sep 2024. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.

### Official description

An issue was discovered in Vaultwarden (formerly Bitwarden_RS) 1.30.3. A stored cross-site scripting (XSS) or, due to the default CSP, HTML injection vulnerability has been discovered in the admin dashboard. This potentially allows an authenticated attacker to inject malicious code into the dashboard, which is then executed or rendered in the context of an administrator's browser when viewing the injected content. However, it is important to note that the default Content Security Policy (CSP) of the application blocks most exploitation paths, significantly mitigating the potential impact.

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

Check this codebase for CVE-2024-39926 and fix it if it is affected.

What it is: CVE-2024-39926 is a medium-severity cross-site scripting vulnerability in n/a, published on 13 Sep 2024. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.
Exploitation: There is no known exploitation of CVE-2024-39926 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.
