CVE-2023-23807Network attack vector

Administrator-level stored XSS via unsanitized settings

Published Jun 22, 2023 · Updated Apr 28, 2026

Stored cross-site scripting in Qumos MojoPlug Slide Panel 1.1.2 and earlier allows remote authenticated users to inject scripts via admin settings. The plugin stores administrator-supplied panel setting values without sufficient input sanitization and renders them without adequate output escaping. Administrator-level access is required, and exploitation affects multisite installations or sites where unfiltered_html is disabled, causing the stored script to run when a user opens an injected page.
