CVE-2026-10086Network attack vector

Session code execution via unsanitized dashboard input

Published Jun 25, 2026 · Updated Jun 25, 2026

Stored XSS in the GitLab EE Analytics Dashboard allows remote authenticated users to execute code in another user's browser session. The dashboard renders user-supplied input without adequate sanitization, but GitLab has not disclosed the affected field or rendering sink. Exploitation requires Developer-role permissions and a targeted user to view the crafted dashboard content, exposing that user's session data and actions.
