Executive Summary

This vulnerability is a stored cross-site scripting (XSS) issue in JetBrains TeamCity versions before 2026.2, 2026.1.4, and 2025.11.8. It allows attackers with low privileges to inject malicious scripts into the classic project overview page, which are then stored and executed when other users view the page.

An attacker could steal session cookies, perform actions on behalf of users, or deface the TeamCity interface. Users with access to the affected project overview could have their accounts compromised or sensitive data exposed through the injected scripts.

Compliance Impact

This vulnerability could lead to unauthorized access to personal or sensitive data, violating GDPR's data protection principles or HIPAA's security requirements. Organizations may face compliance violations, fines, or reputational damage if exploited.

Mitigation Strategies

Update JetBrains TeamCity to version 2026.2, 2026.1.4, or 2025.11.8 or later to address the stored XSS vulnerability in the classic project overview.
