Summary

TypeBot versions up to 3.15.2 have an SSRF vulnerability via Open Redirect Bypass. The validateHttpReqUrl() function blocks private IPs and cloud metadata hosts, but HTTP clients (ky and fetch) follow 302 redirects without re-validating the destination.

Risk Assessment

An authenticated user can point a bot block to an attacker-controlled server that redirects to an internal IP, allowing access to AWS metadata, private subnets, and container services, potentially leading to IAM credential theft.

Recommendation

Update TypeBot to version 3.16.0 or later, which fixes this vulnerability.

Original NVD description (English source)

TypeBot is a chatbot builder tool. Versions 3.15.2 and prior contain an SSRF via Open Redirect Bypass as the HTTP Request block and Code block validate the initial request URL via validateHttpReqUrl() to block private IPs and cloud metadata hostnames. However, the HTTP clients (ky and fetch) follow 302 redirects without re-validating the redirect destination. An authenticated user can point a bot block to an attacker-controlled server that responds with a redirect to an internal IP, causing the Typebot server to reach internal services. An authenticated Typebot user can reach AWS metadata (169.254.169.254), private subnets, and container-internal services. Exploitable to extract cloud IAM credentials or probe internal APIs inaccessible from the internet. This issue has been fixed in version 3.16.0.
