Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

Auth Bypass: The CWD/CDUP command handler incorrectly checked read permissions rather than execute permissions when transitioning directories, allowing users to traverse directories they do not have rights to execute.

Auth Bypass: DeleCommandHandler and RmdCommandHandler permitted unauthorized deletion of files and directories by failing to validate that the active user possesses write permissions on the parent directory containing the target path.

Auth Bypass: The LIST and NLST commands exposed mock file listings to unauthenticated or unauthorized users due to missing read permission verification checks on target directories.
