Stored XSS via unneutralized Tracker Name

Published Dec 26, 2023 · Updated Aug 27, 2024

Stored cross-site scripting in openCRX 5.2.0 allows remote authenticated users to execute script in another user's browser. The Activity Tracker Name field stores unneutralized HTML and renders it across activity lists after the tracker is saved. A low-privileged account must save the tracker, and another user must view an affected list, exposing session data or enabling actions in that browser context.
