Information Disclosure Vulnerability in YesWiki by YesWiki Team

CVE-2025-24019

Summary

YesWiki is at risk due to a vulnerability in versions up to and including 4.4.5, where any authenticated user can manipulate the file manager to delete files owned by the user executing the FastCGI Process Manager (FPM). This flaw enables malicious users to erase significant content, potentially leading to website defacement and data loss. Particularly in standard installations where www-data user ownership of PHP files coincides, users can execute deletions that may paralyze access to the wiki by removing essential files like index.php. A patch addressing this concern has been released in version 4.5.0.
