## What is CVE-2026-39965?

CVE-2026-39965 is a high-severity server-side request forgery vulnerability in baptisteArno typebot.io, published on 22 May 2026. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

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.

Weakness: CWE-918 (Server-Side Request Forgery)
