- Public proof-of-concept exploit exists (CISA SSVC)
[ Description ]Official description
FileRise is a self-hosted web-based file manager with multi-file upload, editing, and batch operations. Prior to 3.18.0, FileRise upload-enabled shared-folder and upload-only links do not reject a destination filename that already exists. An unauthenticated visitor with a valid share token and any configured share password can upload a file with the same name as an existing file and silently replace its content while the original uploader metadata remains. The same replacement gap affects ordinary authenticated uploads through /api/upload/upload.php and authenticated upload-only users who lack edit authority over the existing file. This issue is fixed in version 3.18.0.
