PeerTube is an ActivityPub-federated video streaming platform. Prior to 8.2.2, server-side-rendered video watch pages embed a schema.org JSON-LD block by JSON.stringify-ing video metadata without escaping less-than, greater-than, or slash characters, allowing a value containing the byte sequence that closes a script element to inject arbitrary HTML or JavaScript that executes in the instance origin for visitors to the attacker's videos. This issue is fixed in version 8.2.2.
