CVE-2022-1948Public exploitNetwork attack vector

Stored XSS via unescaped contact names

Published Jul 28, 2022 · Updated Aug 3, 2024

Stored XSS in GitLab 15.0.0 allows remote authenticated users to execute JavaScript in another user's browser through contact details. The CRM contact preview used by the /add_contacts quick action renders attacker-controlled first and last names without HTML escaping. A registered account must create the contact, and a victim must view its preview; the script then acts with the victim's browser privileges.
