Type: advisorySource: Official CVE List1 source record

YesWiki before 4.6.7 contains an access control vulnerability allowing unauthenticated attackers to overwrite any existing wiki page, including pages whose write ACL restricts editing, via the Bazar entry-creation flow. Attackers can submit a crafted entry with an attacker-controlled id_fiche matching an existing page, overwriting its body for mass defacement and content destruction.
