YesWiki before 4.7.0 contains a server-side request forgery vulnerability in DuplicationManager::downloadFile() that allows authenticated administrators to make arbitrary outbound requests via the files array. Attackers can POST file:// or internal URLs to /api/pages/{tag}/duplicate, storing local files, cloud metadata, or database credentials in the publicly accessible files/ directory.
