Name of the Vulnerable Software and Affected Versions
YesWiki versions prior to 4.6.7
Description
An authentication bypass exists in the ActivityPub inbox due to a failure to bind the verified HTTP signature signer to the activity actor. This allows unauthenticated attackers possessing any ActivityPub keypair to send signed Delete or Update activities. By referencing a mirrored entry's
sourceUrl, an attacker can delete or overwrite federated entries belonging to other actors.Recommendations
Update to version 4.6.7 or later.
