Deeper analysis

The vulnerability CVE-2024-36366 is a cross-site scripting flaw (CWE-79) present in JetBrains TeamCity versions prior to 2022.04.7, 2022.10.6, 2023.05.6, and 2023.11.5. It can be triggered through specific report grouping and filtering operations and carries a CVSS 3.1 score of 5.4 reflecting network attack vector, low complexity, and the need for user interaction.

An unauthenticated attacker can supply crafted input that executes arbitrary script in a victim's browser session when the victim performs report operations, resulting in limited disclosure or modification of data accessible to that user.

The JetBrains advisory published at https://www.jetbrains.com/privacy-security/issues-fixed/ states that the issue is resolved by upgrading to one of the listed fixed releases.

The associated EPSS score sits at 0.4462 with no recorded rise from a lower baseline.
