- CVE-2026-73211Critical
PeerTube is an ActivityPub-federated video streaming platform. Prior to 8.1.6, ActorFollowModel.updateScore() interpolates the attacker-controlled ActivityPub actor inboxUrl into an SQL query, allowing an unauthenticated remote server to read and write PeerTube database tables, including oAuthToken.accessToken, and take over administrator accounts. This issue is fixed in version 8.1.6.
- CVE-2026-73090Critical
PeerTube is an ActivityPub-federated video streaming platform. Prior to 8.2.2, processUpdateActivity and processUpdateVideo accept an ActivityPub Update containing a Video object without verifying that byActor.url is authorized for the host in videoObject.id, allowing a malicious federated server to rewrite another server's video metadata, visibility, media file, and HLS URLs. This issue is fixed in version 8.2.2.
- CVE-2026-57167Medium
PeerTube before version 8.2.2 contains a server-side cross-site scripting (XSS) vulnerability in video watch pages. When generating a schema.org JSON-LD block, video metadata is stringified without escaping special characters, allowing an attacker to inject arbitrary HTML or JavaScript.
