Summary

An SSRF vulnerability in TypeBot prior to 3.17.2 allows bypassing the URL validator by using the IPv6 unspecified address ::. A workspace editor or creator can configure a server-side HTTP Request block or script fetch to connect to local HTTP services.

Risk Assessment

The risk involves potential SSRF attacks that could lead to unauthorized access to internal network services, potentially exposing sensitive data or enabling further attack escalation within the organization's infrastructure.

Recommendation

Immediately update TypeBot to version 3.17.2 or later, which includes a fix that blocks the IPv6 :: address in the SSRF validator.

Original NVD description (English source)

TypeBot is a chatbot builder tool. Prior to 3.17.2, Typebot's shared SSRF validator in packages/lib/src/ssrf/validateHttpReqUrl.ts can be bypassed with the IPv6 unspecified address :: because validateIPAddress blocks local, metadata, and private ranges but does not block :: or its expanded form. A workspace editor or creator can configure a server-side HTTP Request block or guarded script fetch to make the Typebot server connect to local HTTP services through safeKy, including flows triggered by POST /v1/typebots/{publicId}/startChat or POST /v1/sessions/{sessionId}/continueChat. This issue is fixed in version 3.17.2.
