Recurring patterns

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

Deserialization of Untrusted Data: Loading untrusted metadata files containing serialized Python pickles allowed arbitrary remote code execution. The fix restricted unpickling using a dedicated SafeUnpickler subclass.

Auth Bypass: A critical authorization check for deleting a database was implemented asynchronously but was not awaited. This meant the check was skipped entirely, permitting unauthorized database deletion.

SQL Injection: The update paths for collection properties utilized unsafe string-formatting rather than parameterized queries during ClickHouse ALTER TABLE UPDATE command execution, creating direct opportunities for SQL injection.
