Recurring patterns

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

Deserialization of Untrusted Data: Multiple fixes migrated away from pickle to safer serialization (jsonpickle, json, skops) because pickle.load allows arbitrary code execution when loading untrusted model/config files.

Path Traversal: Unsafe tarfile.extractall allowed writing files outside the extraction directory, leading to file overwrite (CVE-2021-41127) and directory traversal (CVE-2021-42556). Fixed by switching to tarsafe.

Auth Bypass: Slack webhook endpoints lacked mandatory signature validation, allowing spoofed payloads. Two fixes enforced signing secret verification.
