Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
This vulnerability allows any authenticated user to cause the server to consume very large amounts of disk space when extracting a Zip Bomb. 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. The yauzl library does not contain any mechanism to detect or prevent extraction of a Zip Bomb https://en.wikipedia.org/wiki/Zip_bomb . Therefore, when using the User Import functionality with a Zip Bomb, PeerTube will try extracting the archive which will cause a disk space resource exhaustion.

Upgrade available Upgrade to 7.1.1 or later
Fixed in 7.1.1
Recommended fix High confidence

PeerTube 7.1.1

  1. Backup your PeerTube database and configuration files before proceeding
  2. Stop the PeerTube service to prevent data inconsistency during upgrade
  3. Update PeerTube to version 7.1.1 or later using your installation method (e.g., package manager, Docker, or manual update)
  4. After upgrade, verify that the yauzl library has been updated to include zip bomb protection or that the import functionality now includes extraction limits
  5. Restart the PeerTube service and verify the application is running correctly
  6. Test the user import functionality with a legitimate archive to confirm it still works properly
Caveat Review PeerTube 7.1.1 release notes for any breaking changes between your current version and 7.1.1; minor version upgrades typically have minimal breaking changes but custom plugins/themes may require updates
