Mitigation und Workarounds
The primary mitigation for CVE-2026-7377 is to immediately upgrade GitLab EE to version 18.11.3 or later. If upgrading is not immediately feasible, consider restricting access to customizable analytics dashboards to trusted users only. Implement strict input validation and output encoding on all user-supplied data within the dashboards. While a WAF might offer some protection, it's not a substitute for patching the vulnerable GitLab instance. After upgrading, verify the fix by attempting to inject a simple JavaScript payload into a customizable analytics dashboard and confirming that it is properly sanitized.
