Stored XSS via unsanitized language configuration
Published Apr 17, 2024 · Updated Nov 22, 2024
Stored cross-site scripting in CMSimple 5.15 allows remote attackers to execute arbitrary JavaScript or HTML through the Language Configuration field. CMSimple persists the crafted Configuration value from the Language settings page and later renders it as active markup without neutralizing script content. Reachability requires access to that settings form; execution occurs in the browser context displaying the stored value, enabling page-content changes and browser-accessible data exposure.
