Deeper analysis
CVE-2024-24937 is a stored cross-site scripting vulnerability (CWE-79) affecting JetBrains TeamCity versions prior to 2023.11.2. The flaw resides in the agent distribution functionality and permits persistent injection of malicious scripts that are later rendered in the context of other users' browsers.
An attacker with low-privileged network access can supply crafted input during agent distribution that is stored by the server. When a victim user views the affected page, the script executes with limited impact on confidentiality and integrity, consistent with the CVSS 4.6 rating that requires user interaction and does not affect availability.
JetBrains addressed the issue in TeamCity 2023.11.2, as documented in their published list of resolved security issues. The EPSS score rose sharply from a low baseline to a peak of 0.4109 on 2025-12-11 before receding, indicating a period of increased exploitation interest after disclosure.
