In versions 3.15.2 and prior, the fix for GHSA-4xc5-wfwc-jw47 (\"Credential Theft via Client-Side Script Execution and API Authorization Bypass\") is incomplete. While the builder's getCredentials tRPC endpoint was patched with workspace membership checks, the bot-engine runtime still allows any authenticated user to use credentials from any workspace via the preview chat endpoint. The bot-engine's getCredentials() utility function uses a falsy check (if (workspaceId && ...)) for workspace ownership validation. Since the preview endpoint accepts a client-controlled workspaceId field and the Zod schema allows empty strings, an attacker can supply workspaceId: \"\" to bypass credential ownership verification entirely. Exploitation can result in credential exfiltration, external service abuse, financial damage and a data breach."}, {"lang": "es", "value": "TypeBot es una herramienta de creaci\u00f3n de chatbots.
