CVE-2026-116825

MediumCVSS 6.5/10Last modified Nov 2, 2026

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.
