Frequently Asked Questions

What is CVE-2026-48766?

TypeBot is a chatbot builder tool. Versions prior to 3.17.0 allow a low-privilege guest member of a workspace to exfiltrate stored OpenAI-compatible API keys by invoking the OpenAI model-listing helper with an attacker-controlled `baseUrl`. The vulnerable path decrypts the selected workspace credential, creates an OpenAI client with the secret in both `apiKey` and the explicit `api-key` header, and then sends the outbound request to the caller-supplied URL. Because the permission check accepts any readable workspace member and `listCredentials` reveals credential identifiers to guests, a guest can force the server to deliver the workspace secret to attacker infrastructure. Version 3.17.0 patches the issue.

Is CVE-2026-48766 actively exploited?

No confirmed active exploitation of CVE-2026-48766 has been reported, but organizations should still patch proactively.

Weaknesses (CWE)

CWE-200 — Exposure of Sensitive Information to an Unauthorized Actor: The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information.

  • [Architecture and Design] Compartmentalize the system to have "safe" areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area. Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
