Who should care

Security and platform teams responsible for self-managed GitLab CE/EE, especially internet-facing deployments, as well as incident response and vulnerability management teams tracking KEV items.

Technical summary

The supplied corpus identifies CVE-2023-7028 as an improper access control issue in GitLab CE/EE. The available official records in this corpus do not provide version ranges or deeper technical mechanics, so the safest assessment is that the flaw can weaken expected authorization boundaries in affected GitLab deployments. CISA’s KEV listing indicates confirmed exploitation in the wild.

Defensive priority

High. KEV inclusion means this should be prioritized ahead of routine backlog work, with immediate focus on exposed instances and any environment that stores source code, credentials, or CI/CD secrets in GitLab.

Recommended defensive actions

  • Apply the vendor-recommended mitigation or update path referenced by GitLab’s critical security release materials.
  • If mitigations are unavailable, discontinue use of the affected product as CISA directs for KEV entries.
  • Inventory all GitLab CE/EE instances, including test, staging, and self-managed deployments, and confirm which are externally reachable.
  • Prioritize remediation for any instance that may expose repositories, tokens, runners, or other sensitive development assets.
  • Validate after remediation that access controls and authorization behavior match expectations for project, group, and administrative boundaries.
  • Track this CVE as a KEV item through the 2024-05-22 due date and verify closure in vulnerability management records.

Evidence notes

CISA KEV source item labels CVE-2023-7028 as ‘GitLab Community and Enterprise Editions Improper Access Control Vulnerability,’ adds it on 2024-05-01, and sets a due date of 2024-05-22. The KEV metadata also says to apply mitigations per vendor instructions or discontinue use if mitigations are unavailable, and it references GitLab’s critical security release page and NVD.
