Impact
The cloudstore.file.upload action in server/actions/action_cloudstore_file_upload.go writes user-supplied filenames directly to disk without proper validation.
This allows unauthenticated attackers to perform path traversal and zip slip attacks, leading to arbitrary file write and potential remote code execution.
