Recurring patterns

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

Auth Bypass: The client connection registry lacked verification of host audience claims (allowed_hosts) inside token credentials, allowing potential disclosure of JWTs to untrusted external servers. Developers must ensure all token propagation is explicitly restricted to validated host lists.

Memory Corruption: The code generator was producing unsafe union copy-constructors and uninitialized assignments in C++ serialization, causing undefined behavior and memory corruption. Rust/C++ bridge serialization code should always employ placement-new initialization pattern constraints for non-trivial types.

Command Injection: Workflow actions processed untrusted user context directly in shell scripts (e.g., branch names or PR comment bodies), leading to remote command execution. Future workflows must map all dynamic input to intermediate environment variables rather than direct inline bash interpolation.
