Recurring patterns

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

Remote Code Execution: Deserializing untrusted python user-defined functions (UDFs) via the registry server allows arbitrary remote code execution on the server hosting the Feast registry. This is a critical pattern also seen in CVE-2026-56121.

Auth Bypass: A fail-open permission evaluation vulnerability allowed requests to bypass access controls when permissions were empty or unmatched. Implementing a strict denial-by-default posture is necessary to protect downstream services.

Code Injection: Using unsafe yaml.load with FullLoader allowed attackers with write access to specific configurations to execute arbitrary code via malicious YAML files. Replaced by yaml.safe_load.
