CVE-2025-61949Network attack vector

Authenticated script execution via stored user information

Published Nov 21, 2025 · Updated Nov 21, 2025

Stored XSS in UserManagement in LogStare Collector 2.4.1 and earlier allows remote authenticated users to execute browser scripts. UserManagement stores crafted user information and later renders it in the management page without neutralizing script content; no finer code locus is public. A low-privileged user must save crafted account data, and execution occurs only when another user logs in to the management page, exposing or altering data within that browser session.
