CVE-2025-11927Network attack vector

Stored XSS via unvalidated lazyload margin setting

Published Nov 1, 2025 · Updated Nov 1, 2025

Stored XSS in Flying Images 2.4.14 and earlier allows remote authenticated users to inject scripts through the lazyload margin setting. The settings handler stores the administrator-supplied margin without adequate validation, allowing it to be emitted into generated lazy-loading JavaScript without sufficient escaping. Administrator access is required, and exposure is limited to multisite installations or sites where unfiltered_html is disabled; injected code runs in visitors' browser contexts.
