In versions 3.15.2 and prior, the preview chat endpoint (POST /api/v1/typebots/{typebotId}/preview/startChat) allows unauthenticated users to achieve Server-Side Request Forgery (SSRF) by supplying a custom typebot definition with server-side code blocks. The fetch function exposed inside the isolated-vm sandbox calls Node.js native fetch without the SSRF validation (validateHttpReqUrl) that protects the HTTP Request block. This bypasses all SSRF mitigations added after GHSA-8gq9-rw7v-3jpr. Exploitation of this unauthenticated SSRF vulnerability can lead to cloud credential theft, internal network access and data exfiltration for any self-hosted Typebot deployments and hosted services. This issue has been fixed in version 3.16.0." } ], "source": { "advisory": "GHSA-vc2q-r6rq-ggj9", "discovery": "UNKNOWN" } }, "adp": [ { "references": [ { "url": "https://github.com/baptisteArno/typebot.io/security/advisories/GHSA-vc2q-r6rq-ggj9", "tags": [ "exploit" ] } ], "metrics": [ { "other": { "type": "ssvc", "content": { "timestamp": "2026-05-22T17:18:33.583327Z", "id": "CVE-2026-33712", "options": [ { "Exploitation": "poc" }, { "Automatable": "yes" }, { "Technical Impact": "total" } ], "role": "CISA Coordinator", "version": "2.0.3" } } } ], "title": "CISA ADP Vulnrichment", "providerMetadata": { "orgId": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "shortName": "CISA-ADP", "dateUpdated": "2026-05-22T17:19:14.917Z" } } ] } }
