YesWiki from 4.6.2 before 4.7.0 contains a missing authorization vulnerability in ActivityPubService::syncActorPosts that lets malicious ActivityPub servers manipulate other actors' mirrored entries. Attackers can serve a poisoned outbox with cross-actor Delete, Update, or Create activities during admin-initiated sync to delete, overwrite, forge, or mass-delete entries.
