CVE-2024-8479: Webliberty Simple Spoiler

High severity, CVSS 7.3. EPSS: 0.6% chance of exploitation in the next 30 days.

The The Simple Spoiler plugin for WordPress is vulnerable to arbitrary shortcode execution in versions 1.2 to 1.3. This is due to the plugin adding the filter add_filter('comment_text', 'do_shortcode'); which will run all shortcodes in comments. This makes it possible for unauthenticated attackers to execute arbitrary shortcodes.

Affected products

• Webliberty Simple Spoiler: from 1.2, before 1.4 (fixed in 1.4)
