CVE-2026-61843 Details
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.
A vulnerability in FileRise prior to version 3.18.0 allows unauthenticated users to overwrite existing files in folders shared with upload-enabled links. The issue arises because the application does not check for filename collisions before replacing files. This vulnerability also affects authenticated users with upload-only permissions who lack editing rights over the files being replaced.
Users can update to FileRise version 3.18.0, which addresses this vulnerability by rejecting filename collisions in shared uploads and requiring edit authority for overwriting files in authenticated uploads.
