Orijinal NVD Açıklaması

File Browser is a file managing interface for uploading, deleting, previewing, renaming, and editing files within a specified directory. Prior to 2.63.16, a scoped, non-admin File Browser user holding only the Create permission can delete arbitrary files outside their scope (other tenants' data, and the application's own database) via the upload failure-cleanup path. ScopedFs.RemoveAll is the one dereferencing operation that skips the symlink guard every other method enforces. The direct-upload handler runs RemoveAll on the user-controlled path during failed-upload cleanup, gated only by Perm.Create. If an escaping directory symlink already exists inside the user's scope, an authenticated create-only user can delete an out-of-scope target, bypassing both the ScopedFs boundary and the Perm.Delete gate. This vulnerability is fixed in 2.63.16.
