CVE-2025-23440Network attack vector

Authenticated stored XSS via undisclosed authorization flaw

Published Mar 3, 2025 · Updated Apr 28, 2026

Missing authorization in RadicalDesigns radSLIDE 2.1 and earlier allows remote authenticated users to inject stored scripts. Patchstack identifies broken access control leading to stored cross-site scripting but does not disclose the affected handler, parameter, or missing authorization check. Low-privileged WordPress access is required, and successful exploitation stores attacker-controlled script content for later delivery.
