Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Deserialization: The codebase adopted PickleSerializer for network messages, which permits arbitrary object injection and immediate remote code execution via unsafe pickle.loads deserialization over the network protocol.
Code Execution: Loading custom User-Defined Functions (UDFs) directly from disk files allows arbitrary Python execution if the loader executes unverified or tampered files without validating their integrity checksums against the system catalog.
Path Traversal: User-controlled file paths and upload destinations bypass security controls if they are not constrained to a safe root directory using a validated path-joining mechanism.
