LOW 2.7

Published 2026-10-21 · Last modified 2026-10-21

GitLab has remediated an issue in GitLab EE affecting all versions from 19.2 before 19.3.6, 19.4 before 19.4.3, and 19.5 before 19.5.1 that, when an instance administrator locked a group's Duo availability, an authenticated user with group Owner permissions could have re-enabled AI-backed data egress to a third-party service for that group and its descendant projects, due to insufficient granularity of the admin-lock enforcement controls.
