3 high-severity fixes in this history; regressions here are high-impact.
Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Secret Exposure: Hardcoded production API keys and Redis passwords in version control are a direct path to credential theft and payment infrastructure compromise; this was the most severe historical issue.
Access Control Bypass: Unauthorized tool invocation could allow arbitrary MCP operations; the fix enforces an exact TOOLS allowlist before callTool, but sibling paths (e.g., ListTools or future tool registrations) must enforce the same check.
Cryptographic Weakness: Weak certificate generation undermines mutual TLS authentication; the fix adds SAN and key usage extensions, but all certificate generation and validation paths must use these hardened defaults.
