Analysis Summary

GitLab has released critical security updates for its Community Edition (CE) and Enterprise Edition (EE) to address multiple vulnerabilities, including a high-severity cross-site scripting (XSS) flaw. Updated versions 17.8.1, 17.7.3, and 17.6.4 have been made available to mitigate these issues.

The most critical vulnerability, CVE-2025-0314, has a CVSS score of 8.7 and affects all versions from 17.2 to 17.6.3, 17.7 to 17.7.2, and 17.8 to 17.8.0. This flaw arises from the improper rendering of certain file types, enabling attackers to inject malicious scripts. Exploitation could lead to session hijacking, data theft, or system compromise. GitLab advises users to update to the patched versions immediately.

Additionally, two other vulnerabilities have been resolved:

• CVE-2024-11931: A medium-severity flaw (CVSS score 6.4) allowing developers to exfiltrate protected CI/CD variables via CI lint.
• CVE-2024-6324: A medium-severity denial-of-service (DoS) vulnerability (CVSS score 4.3) caused by cyclic references in epics.

GitLab strongly recommends all users to upgrade their installations promptly to secure their systems against these threats. For further details, refer to GitLab's official advisory.
