Unauthenticated command execution via unsanitized id parameter
Published Jul 1, 2026 · Updated Jul 1, 2026
OS command injection in The Guardian Language System allows remote attackers to execute arbitrary server commands through the id parameter. In src/transcribe.php, the id GET value is concatenated without sanitization into a shell command passed to PHP exec(), allowing shell metacharacters to introduce additional commands. The endpoint is reachable without authentication, and command output is blind, but injected commands run with the web-server process's operating-system privileges.
