AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:N

Name of the Vulnerable Software and Affected Versions TypeBot versions prior to 3.15.3

Description An incomplete fix in the bot-engine runtime allows authenticated users to use credentials from any workspace via the preview chat endpoint. The getCredentials() utility function employs a falsy check for workspace ownership validation. Because the preview endpoint accepts a client-controlled workspaceId field and the Zod schema allows empty strings, providing workspaceId: "" bypasses credential ownership verification. This can lead to credential exfiltration, external service abuse, financial damage, and data breaches.

Recommendations Update to a version later than 3.15.2.
