CVE-2025-14871
HIGH 7.5GitLab has remediated an issue in GitLab CE/EE affecting all versions from 18.4.6 before 19.1.8, 19.2 before 19.2.6, and 19.3 before 19.3.2 that under certain conditions could have allowed an unauthenticated user to cause denial of service due to improper resource allocation limits in the GraphQL complexity calculation logic.
Severe if exploited (CVSS 7.5), but no known exploitation and low modeled probability. Patch on a normal cadence.
