CVE-2025-14560 is a cross-site scripting vulnerability in the Code Flow functionality of GitLab Community Edition and Enterprise Edition. It affects all versions from 17.1 before 18.6.6, 18.7 before 18.7.4, and 18.8 before 18.8.4. Under certain conditions, an authenticated user can inject malicious content into the vulnerability code flow, which is then rendered in another user's browser. When the injected content is viewed, attacker-controlled script can execute in the victim's session context and be used to trigger actions as that user.
