CVE-2021-38615Network attack vector

SSO configuration tampering via missing authorization

Published Sep 7, 2021 · Updated May 30, 2025

Missing authorization in Eigen NLP 3.10.1 allows remote authenticated users to read and modify SSO configuration over the network. The /auth/v1/sso/config/ endpoint processes configuration-view and modification requests from any logged-in account without enforcing role-based access control. Guest-level access is sufficient, and published evidence does not identify the exposed SSO fields or the authentication effects of modifying them.
