GitLab Security Update – Patch for Multiple Vulnerabilities

GitLab, the widely adopted DevOps platform, has announced the immediate release of versions 17.8.1, 17.7.3, and 17.6.4 for both its Community Edition (CE) and Enterprise Edition (EE).

These updates address multiple security vulnerabilities and provide critical fixes, underscoring GitLab’s commitment to maintaining the highest security standards.

The vulnerabilities addressed in these updates include a high-severity Stored XSS via Asciidoctor render, a medium-severity issue where a developer could exfiltrate protected CI/CD variables via CI lint, and another medium-severity vulnerability involving cyclic references of epics leading to resource exhaustion.

GitLab strongly encourages self-managed users to upgrade to the latest versions immediately to safeguard their systems.

GitLab has already deployed these updates on GitLab.com, meaning users on the hosted platform are automatically protected. GitLab Dedicated customers do not need to take action. However, self-managed GitLab users are urged to:

1. Upgrade to one of the patched versions (17.8.1, 17.7.3, or 17.6.4) immediately.
2. Follow best practices for securing GitLab instances, which are outlined in GitLab’s official blog.

GitLab remains steadfast in prioritizing security by addressing vulnerabilities through timely patches.

Security issues are made public 30 days after patch releases to ensure transparency while protecting vulnerabilities during the critical update window.
