CVE-2024-3337: Extendthemes Colibri Page Builder

Medium severity, CVSS 5.4. EPSS: 0.4% chance of exploitation in the next 30 days.

The Colibri Page Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'colibri_breadcrumb_element' shortcode in all versions up to, and including, 1.0.272 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Affected products

• Extendthemes Colibri Page Builder: before 1.0.274 (fixed in 1.0.274)
