CVE-2024-1051: Fernandobt List Category Posts

Medium severity, CVSS 6.4. EPSS: 0.4% chance of exploitation in the next 30 days.

The List category posts plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'catlist' shortcode in all versions up to, and including, 0.89.6 due to insufficient input sanitization and output escaping on user supplied attributes like 'title_tag'. This makes it possible for authenticated attackers with contributor-level and above permissions to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Affected products

• Fernandobt List Category Posts: up to and including 0.89.6
