 """
 PoC test for CWE-22 path traversal in LocalStorageProvider.
 The LocalStorageProvider uses os.path.join(LOCAL_STORAGE_PATH, key) without
 validating that the resulting path stays inside LOCAL_STORAGE_PATH.
 When `key` is an absolute path (e.g. '/etc/passwd'), os.path.join discards
 all previous components and returns the absolute path directly, allowing
 arbitrary file reads, writes, and deletes.
 This test must FAIL before the fix and PASS after.
