Stored Cross-Site Scripting in Colibri Page Builder Plugin for WordPress

CVE-2025-9560

What is CVE-2025-9560?

The Colibri Page Builder plugin for WordPress is vulnerable to stored cross-site scripting through its colibri_newsletter shortcode. This vulnerability arises from inadequate input sanitization and output escaping of user-supplied attributes, allowing authenticated attackers with contributor-level access or higher to inject arbitrary web scripts into pages. Consequently, these scripts execute whenever a user accesses the affected page, potentially leading to unauthorized actions or data exposure.
