CVE-2024-4361: Siteorigin Page Builder

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

The Page Builder by SiteOrigin plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'siteorigin_widget' shortcode in all versions up to, and including, 2.29.15 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

• Siteorigin Page Builder: before 2.29.16 (fixed in 2.29.16)
