Administrator-level stored XSS via unsafe settings rendering
Published Feb 19, 2026 · Updated Feb 19, 2026
Stored XSS in Ben Holland Slidorion 1.0.2 and earlier allows remote authenticated users to execute scripts through admin settings. The settings handler stores administrator-supplied values without sufficient sanitization, and the plugin later renders them without output escaping. Administrator access and either WordPress multisite or disabled unfiltered_html are required; the stored payload runs when an affected page is viewed.
