Deeper analysis
CVE-2022-48428 is a stored cross-site scripting vulnerability (CWE-79) affecting the SSH keys page in JetBrains TeamCity versions prior to 2022.10.3. The flaw carries a CVSS 3.1 base score of 4.6 and stems from insufficient sanitization of user-supplied content persisted on that page.
An authenticated attacker with low privileges can store a malicious script that executes in the browsers of other users who later view the SSH keys page, resulting in limited disclosure or modification of information. Exploitation requires user interaction and does not impact availability.
JetBrains addressed the issue in TeamCity 2022.10.3, as noted in their published list of fixed security issues. The associated EPSS score rose from a low baseline to a peak of 0.0566 on 2025-12-11 before receding to the current value of 0.0058, indicating a temporary increase in observed exploitation interest after disclosure.
