## What is CVE-2025-11161?

CVE-2025-11161 is a medium-severity cross-site scripting vulnerability in WPBakery Page Builder, published on 15 Oct 2025. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

The WPBakery Page Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the vc_custom_heading shortcode in all versions up to, and including, 8.6.1. This is due to insufficient restriction of allowed HTML tags and improper sanitization of user-supplied attributes in the font_container parameter. This makes it possible for authenticated attackers with contributor-level access or higher to inject arbitrary web scripts in posts that will execute whenever a user accesses an injected page via the vc_custom_heading shortcode with malicious tag and text attributes granted they have access to use WPBakery shortcodes.

Weakness: CWE-80 (Improper Neutralization of Script-Related HTML Tags in a Web Page)
