Administrator-level stored cross-site scripting

Published Apr 11, 2022 · Updated Apr 28, 2026

Patchstack and the CNA record do not disclose the affected field, rendering function, or missing sanitization or output-escaping operation. Administrator or higher access is required to store the payload, and successful exploitation requires another user to load the affected content, where the script can read or alter data exposed to the page.
