Affected versions of this package are vulnerable to External Control of File Name or Path through the deleteFileOrFolder and renameFile processes. An attacker can remove or rename critical application files by sending crafted requests to these endpoints with paths to files outside the intended allowlist. This can result in persistent disruption of the application, requiring filesystem-level intervention to restore functionality. This is only exploitable if the attacker has authenticated backend access with the fileeditor.delete or fileeditor.update permission.
