Misskey is an open source, federated social media platform. The patch for CVE-2024-52591 did not sufficiently validate the relation between the "id" and "url" fields of ActivityPub objects. An attacker can forge an object where they claim authority in the "url" field even if the specific ActivityPub object type require authority in the "id" field. Version 2025.2.1 addresses the issue.
