CVE-2023-33002Network attack vector

Stored XSS via unescaped project name

Published May 16, 2023 · Updated Jan 23, 2025

Stored XSS in Jenkins TestComplete support Plugin 2.8.1 and earlier allows remote authenticated users to execute script in a viewer's browser. The test result page inserts the configured TestComplete project name into rendered output without escaping it, preserving attacker-controlled markup for later viewing. Item/Configure permission is required to store the name, and exploitation occurs when another user opens the affected test result page.
