CVE-2025-70559: Insecure Path Join Pickle Loads
Path traversal leading to insecure deserialization. Using `os.path.join` with uncontrolled inputs and passing the result directly to an `open` call before deserializing with `pickle.loads` allows attackers to bypass boundary checks and execute arbitrary code. Validate paths using `os.path.realpath` and verify directory prefixes before opening.
