This vulnerability has been remediated in the specified fixed versions.
AI Analysis
Technical Summary
GitLab CE/EE versions >=18.2.0 <19.0.6, >=19.1.0 <19.1.4, and >=19.2.0 <19.2.2 contain a cross-site scripting vulnerability due to improper neutralization of user-controlled values in the analytics dashboard's table cell rendering. This could allow an attacker to inject malicious scripts into web pages generated by GitLab under certain conditions. The issue has been fixed in versions 19.0.6, 19.1.4, and 19.2.2 respectively.
Potential Impact
Successful exploitation could allow an attacker to execute arbitrary scripts in the context of the affected GitLab web application, potentially leading to session hijacking, defacement, or other client-side attacks. However, no known exploits in the wild have been reported.
Mitigation Recommendations
A patch is available and users should upgrade to GitLab versions 19.0.6, 19.1.4, or 19.2.2 or later to remediate this vulnerability. No additional mitigations are indicated by the vendor advisory.
