Summary dbcve.org
This is a cross-site scripting (XSS) vulnerability in GitLab CE/EE where an attacker can inject malicious HTML into an email address field. The flaw exists due to insufficient input validation/sanitization on the email field, allowing stored XSS to occur when the injected HTML is rendered in the application.
