CVE-2026-16627 is a cross-site scripting vulnerability in GitLab Community Edition and Enterprise Edition affecting version 19.2 before 19.2.2. The flaw is caused by improper sanitization of HTML content rendered in the CI manual job confirmation modal. Under certain conditions, an authenticated user with developer-role permissions can inject malicious HTML or script content into the modal, leading to script execution in another user's browser session. Because the vulnerable component is part of the CI job workflow, successful exploitation can be leveraged to perform actions in the context of a more privileged user and thereby escalate privileges.
