CVE-2026-81839
HIGH 7.7GitLab has remediated an issue in GitLab EE affecting all versions from 18.1 before 19.2.8, 19.3 before 19.3.5, and 19.4 before 19.4.2 that, under certain conditions, could have allowed an authenticated user to execute arbitrary CI/CD pipelines in a transferred project with the new group's privileges due to improper cleanup of scheduled pipeline execution policy records.
Severe if exploited (CVSS 7.7), but no known exploitation and low modeled probability. Patch on a normal cadence.
