Recurring patterns

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

Auth Bypass: Unauthenticated webhook processors can trigger arbitrary pipeline execution or leak processing metadata. Restricting webhook evaluation via HMAC signature checks is critical to prevent spoofed trigger payloads.

Auth Bypass: Failure to pass proper credentials down to the underlying git client decorator can lead to authentication failures or insecure fallback behaviors during checkout processes.

Missing Authorization: Exposing credentials lookup or system configuration endpoints via Stapler binding without explicit permission checks allows unprivileged users to extract sensitive credential IDs or endpoint layouts.
