CVE-2026-33070 Details
Description
FileRise is a self-hosted web file manager / WebDAV server. In versions prior to 3.8.0, a missing-authentication vulnerability in the deleteShareLink endpoint allows any unauthenticated user to delete arbitrary file share links by providing only the share token, causing denial of service to shared file access. The POST /api/file/deleteShareLink.php endpoint calls FileController::deleteShareLink() which performs no authentication, authorization, or CSRF validation before deleting a share link. Any anonymous HTTP client can destroy share links. This issue is fixed in version 3.8.0.
A missing authentication vulnerability has been identified in FileRise, a self-hosted web file manager and WebDAV server, in versions prior to 3.8.0. The vulnerability exists in the deleteShareLink endpoint, where any unauthenticated user can delete arbitrary file share links by simply providing the share token. This deletion process is executed without any authentication, authorization, or Cross-Site Request Forgery (CSRF) validation, leading to a denial-of-service condition for shared file access. The issue has been fixed in version 3.8.0.
Users are advised to update to FileRise version 3.8.0, which requires authentication and admin privileges for share link deletion, along with a valid CSRF token.
