LiteSpeed Cache < 7.9.2 - Unauthenticated Stored XSS via CDN Inline CSS Rewriting

Published Oct 23, 2026 · Updated Oct 23, 2026 · Assigned by WPScan

Description

The LiteSpeed Cache WordPress plugin before 7.9.2 does not restrict one of its HTML rewriting routines to stylesheet content, so it removes a quote that terminates an attribute in the rendered page, and combined with unescaped comment author output this allows unauthenticated users whose comment is published to inject attributes that execute JavaScript in the browser of any visitor, including a logged-in administrator, who views front-end pages while the affected option is enabled.
