YesWiki versions prior to 4.6.6 contain a critical vulnerability in the erasespamedcomments action that allows unauthenticated users with default write access to delete arbitrary wiki pages without authorization checks. The vulnerability arises from the lack of access control on the {{erasespamedcomments}} action, combined with the default permissive ACL configuration and the absence of validation in the page deletion functions. This permits deletion of any page, including the front page and administrative pages, by sending crafted POST requests. No CSRF protections or per-page authorization checks are performed during deletion.
