File Browser provides a file managing interface within a specified directory and it can be used to upload, delete, preview, rename and edit files. Prior to version 2.61.1, a broken access control vulnerability in the TUS protocol DELETE endpoint allows authenticated users with only Create permission to delete arbitrary files and directories within their scope, bypassing the intended Delete permission restriction. Any multi-user deployment where administrators explicitly restrict file deletion for certain users is affected. This issue has been patched in version 2.61.1.

CVE-2026-29188 [CRITICAL] CWE-284 File Browser's TUS Delete Endpoint Bypasses Delete Permission Check
File Browser's TUS Delete Endpoint Bypasses Delete Permission Check
### Summary
A broken access control vulnerability in the TUS protocol DELETE endpoint allows authenticated users with only Create permission to delete arbitrary files and directories within their scope, bypassing the intended Delete permission restriction. Any multi-user deployment where administrators explicitly restrict file deletion for certain users is affected.
### Details
The tusDeleteHandler function in http/tus_handlers.go incorrectly gates the DELETE operation behind Perm.Create instead of Perm.Delete:
```go
// http/tus_handlers.go - tusDeleteHandler (VULNERABLE)
func tusDeleteHandler(cache UploadCache) handleFunc {
return withUser(func(_ http.ResponseWriter, r *http.Request, d *data) (int, error) {
if r.URL.
