CVE-2026-49213: CWE-918: Server-Side Request Forgery (SSRF) in baptisteArno typebot.io
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.
AI Analysis
Technical Summary
CVE-2026-49213 is a server-side request forgery (SSRF) vulnerability in TypeBot, a chatbot builder tool by baptisteArno. The issue arises because the shared SSRF validator in the code (packages/lib/src/ssrf/validateHttpReqUrl.ts) blocks local, metadata, and private IP ranges but does not block the IPv6 unspecified address (::) or its expanded form. An attacker with workspace editor or creator privileges can exploit this by configuring server-side HTTP request blocks or guarded script fetches to cause the TypeBot server to connect to local HTTP services. This can be triggered through API endpoints such as POST /v1/typebots/{publicId}/startChat or POST /v1/sessions/{sessionId}/continueChat. The vulnerability is resolved in TypeBot version 3.17.2.
Potential Impact
An attacker with workspace editor or creator privileges can exploit this SSRF vulnerability to make the TypeBot server initiate HTTP requests to internal local services that are normally inaccessible externally. This can lead to unauthorized access to internal resources and potentially compromise confidentiality and integrity of data accessible via these internal services. The CVSS score of 8.1 reflects high impact on confidentiality and integrity with no impact on availability.
Mitigation Recommendations
Upgrade TypeBot to version 3.17.2 or later, where this SSRF vulnerability is fixed by properly blocking the IPv6 unspecified address (::) in the SSRF validator. Until upgrade, restrict workspace editor and creator privileges to trusted users only to reduce risk. Patch status is confirmed fixed in 3.17.2.
