Contributor-level stored XSS via unsanitized page content

Published Sep 5, 2025 · Updated May 13, 2026

Stored cross-site scripting in ARI Soft ARI Fancy Lightbox 1.4.0 and earlier allows remote authenticated users to execute scripts in pages. Contributor-supplied page content is retained and later rendered without sufficient input sanitization and output escaping, so injected scripts run when the page is viewed. Contributor-level access is required; execution occurs in a visitor's browser and can alter displayed content or act with that visitor's site privileges.
