Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Deserialization of Untrusted Data: The metrics protobuf unmarshalling path relies on gogo/protobuf, which had a known deserialization vulnerability (CVE-2021-3121) fixed by a dependency bump. Any future use of an older or unpatched gogo/protobuf version re-exposes this sink.
Command Injection: Deprecated GitHub Actions set-env/add-path commands allowed injection of arbitrary commands via crafted input. The fix replaced them with environment files; reintroducing those commands would recreate the vulnerability.
