Summary dbcve.org
A reflected cross-site scripting (XSS) vulnerability exists in GitLab CE/EE abuse report creation functionality across versions 15.8 through 16.0.2. Attackers can craft malicious URLs containing JavaScript payloads that execute in victims' browsers when they create new abuse reports, enabling session hijacking and actions performed on behalf of authenticated users.
