Technical description

FileRise is a self-hosted web-based file manager with multi-file upload, editing, and batch operations. Prior to 3.14.0, FileRise authenticates requests to the file creation and share-link creation handlers but does not enforce the server-side CSRF token check used by adjacent state-changing operations. The POST endpoints /api/file/createFile.php and /api/file/createShareLink.php invoke FileController::createFile and FileController::createShareLink without rejecting a missing or invalid X-CSRF-Token header. A request issued with a logged-in user's session can create an empty file or create a share link with that user's permissions, although the default SameSite=Lax session cookie reduces ordinary cross-site POST reachability. This issue is fixed in version 3.14.0.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
