CVE-2023-33007Network attack vector

Stored XSS via unescaped test result name

Published May 16, 2023 · Updated Jan 23, 2025

Stored XSS in LoadComplete support Plugin 1.0 and earlier allows remote authenticated users to execute script in a viewer's browser. The plugin writes a configured LoadComplete test name into its test result page without escaping it, so a crafted name becomes executable page content. Item/Configure permission is required to store the name, and exploitation occurs when another user views the affected test result page.
