CVE-2026-48766: TypeBot workspace credential exposure through OpenAI model-listing helper

Source: NVD(opens in a new tab)
Identifier: CVE-2026-48766
Published: August 11, 2026
Record updated: October 9, 2026

Known exploitation: Not listed in the CISA Known Exploited Vulnerabilities catalog at the last check.
EPSS: 0.4%

Summary

TypeBot versions prior to 3.17.0 let a low-privilege guest member of a workspace exfiltrate stored OpenAI-compatible API keys. The guest calls the OpenAI model-listing helper with an attacker-controlled `baseUrl`, so the server decrypts the workspace credential and sends it, in both `apiKey` and the `api-key` header, to the attacker's URL. The permission check accepts any readable workspace member, and `listCredentials` reveals credential identifiers to guests.

Mitigation

Fixed in 3.17.0.
