## What is CVE-2026-32891?

CVE-2026-32891 is a critical cross-site scripting vulnerability in openVESSL Anchorr, published on 20 Mar 2026. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.

### Official description

Anchorr is a Discord bot for requesting movies and TV shows and receiving notifications when items are added to a media server. Versions 1.4.1 and below contain a stored XSS vulnerability in the Jellyseerr user selector. Jellyseerr allows any account holder to execute arbitrary JavaScript in the Anchorr admin's browser session. The injected script calls the authenticated /api/config endpoint - which returns the full application configuration in plaintext. This allows the attacker to forge a valid Anchorr session token and gain full admin access to the dashboard with no knowledge of the admin password. The same response also exposes the API keys and tokens for every integrated service, resulting in simultaneous account takeover of the Jellyfin media server (via JELLYFIN_API_KEY), the Jellyseerr request manager (via JELLYSEERR_API_KEY), and the Discord bot (via DISCORD_TOKEN). This issue has been fixed in version 1.4.2.

Weakness: CWE-80 (Improper Neutralization of Script-Related HTML Tags in a Web Page), CWE-311 (Missing Encryption of Sensitive Data), CWE-212 (Improper Removal of Sensitive Information Before Storage or Transfer)

Affected product: openVESSL Anchorr. 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.
