Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Local loopback bypass mechanisms combined with missing middleware on utility endpoints allowed attackers to access privileged control routes remotely, especially when the relay was deployed behind reverse proxies or tunnel agents.
DNS Rebinding: The lack of Host header validation in the HTTP endpoints allowed malicious websites to interact with local relay services via DNS rebinding attacks, bypassing local network isolation rules.
Command Injection: Direct shell execution via child_process.exec allowed arbitrary command injection through untrusted, unescaped file paths during media processing.
