CVE-2026-48766: CWE-200: Exposure of Sensitive Information to an Unauthorized Actor in baptisteArno typebot.io
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.
AI Analysis
Technical Summary
CVE-2026-48766 is an information exposure vulnerability in TypeBot (baptisteArno) affecting versions before 3.17.0. A low-privilege guest workspace member can exploit the OpenAI model-listing helper by supplying a malicious baseUrl. The vulnerable code decrypts the workspace's OpenAI API key and sends it in both the apiKey parameter and the explicit api-key header to the attacker-controlled URL. The permission check only requires readable workspace membership, and the listCredentials function reveals credential identifiers to guests, enabling them to force the server to leak sensitive workspace secrets. This vulnerability is classified as CWE-200 (Exposure of Sensitive Information).
Potential Impact
An attacker with guest-level access to a workspace can exfiltrate sensitive OpenAI API keys stored in the workspace. This can lead to unauthorized use of the API keys, potentially incurring costs or data leakage. The vulnerability impacts confidentiality (high), integrity (low), and availability (low) as per the CVSS vector.
Mitigation Recommendations
Upgrade TypeBot to version 3.17.0 or later, where this vulnerability is patched. No other mitigation or temporary workaround is indicated in the available data.
