What fixes it

A fixed version on one release line is not the upgrade target for every line. Check your exact version and any vendor backports.

Description

YesWiki from 4.6.2 before 4.7.0 lacks replay protection in HttpSignatureService::verifySignature(), which never validates the Date header or tracks seen signatures. Attackers who capture a signed request to the /api/forms/{formId}/actor/inbox endpoint can replay it later to re-execute Delete, Update, Follow, or Undo actions.
