Reflected XSS via unsanitized historyvalue
Published Jun 21, 2021 · Updated Aug 3, 2024
Cross-site scripting in WP Hardening before 1.2.2 allows remote attackers to execute script in a victim's browser via a crafted historyvalue GET parameter. The plugin inserts that parameter into a JavaScript block without sanitizing or escaping it, allowing reflected payloads to break out of the script context. Exploitation requires a victim with access to the affected wp-admin page to request the crafted URL; the demonstrated impact is script execution in that browser session.
