Stored XSS via unrestricted media HTML embeds

Published Aug 13, 2026 · Updated Aug 13, 2026

Stored cross-site scripting in WPManageNinja FluentCommunity 2.7.5 and earlier allows remote authenticated users to execute script via media embeds. The media HTML embed path stores subscriber-supplied markup without sufficient restriction and later renders it for other site visitors. Subscriber access is required, and exploitation requires another user to view the crafted content, exposing that browser session to script-controlled actions.
