CVE-2026-48766Public exploitNetwork attack vectorHinoki check available

Guest API key theft via arbitrary model endpoint

Published Aug 11, 2026 · Updated Aug 11, 2026

Credential disclosure in Typebot before 3.17.0 allows remote authenticated users to steal workspace OpenAI-compatible API keys. The handleListModels path decrypts a selected credential and gives its secret to an OpenAI client that sends authentication headers to the caller-controlled baseUrl. Guest workspace membership and a known workspace identifier are sufficient to enumerate a credential ID and deliver the plaintext secret to attacker infrastructure.
