Detailsinfo

A vulnerability was found in baptisteArno Typebot up to 3.16.x. It has been rated as problematic. Affected by this issue is an unknown code of the component OpenAI Model-Listing Helper. The manipulation of the argument baseUrl with an unknown input leads to a permission vulnerability. Using CWE to declare the problem leads to CWE-275. Impacted is confidentiality. CVE summarizes:

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.

The advisory is shared for download at github.com. This vulnerability is handled as CVE-2026-48766 since 05/22/2026. The exploitation is known to be easy. The attack may be launched remotely.
