Technical details
A Server-Side Request Forgery (SSRF) vulnerability exists in TypeBot due to a Time-of-Check to Time-of-Use (TOCTOU) flaw in its URL validation logic. The `validateHttpReqUrl` function resolves a hostname to check against forbidden IP ranges, but the subsequent `fetch` call performs a second, independent DNS resolution using the original hostname rather than pinning the validated IP. An attacker can use DNS rebinding to return a safe IP during the check and a private/internal IP (such as 169.254.169.254) during the actual request. This can be exploited via public chat APIs if a bot is configured to perform server-side HTTP requests or script fetches using user-supplied input. The issue is fixed in version 3.17.2.
