AI Analysis
Technical Summary
CVE-2026-59794 is a stored XSS vulnerability (CWE-79) in JetBrains TeamCity affecting versions prior to 2026.1.2. The issue arises from insufficient sanitization of agent-reported data displayed on the cloud profile page, enabling an attacker with low privileges and requiring user interaction to execute arbitrary scripts in the context of the victim's browser. This can lead to high confidentiality and integrity impact but does not affect availability.
Potential Impact
Successful exploitation allows an attacker to execute arbitrary scripts in the context of a victim user’s browser, potentially leading to theft of sensitive information or manipulation of the user interface. The vulnerability requires low attack complexity and privileges but does require user interaction. There are no known exploits in the wild at this time.
Mitigation Recommendations
