CVE-2021-24525: Getshortcodes Shortcodes Ultimate

Medium severity, CVSS 5.4. EPSS: 0.6% chance of exploitation in the next 30 days.

The Shortcodes Ultimate WordPress plugin before 5.10.2 allows users with Contributor roles to perform stored XSS via shortcode attributes. Note: the plugin is inconsistent in its handling of shortcode attributes; some do escape, most don't, and there are even some attributes that are insecure by design (like [su_button]'s onclick attribute).

Affected products

• Getshortcodes Shortcodes Ultimate: before 5.10.2 (fixed in 5.10.2)
