CyberRota Analysis
AI-GeneratedThe Avada (Fusion) Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting due to inadequate input sanitization and output escaping of the 'size' shortcode attribute in versions up to 3.15.6. This flaw allows authenticated attackers with contributor-level access or higher to inject malicious scripts into pages, which execute when users access those pages. WordPress site administrators using this plugin should prioritize patching to mitigate the risk of exploitation.
Original NVD Description
The Avada (Fusion) Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'size' Shortcode Attribute in all versions up to, and including, 3.15.6 due to insufficient input sanitization and output escaping. 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. WordPress's wp_kses_post filter does not neutralize the payload because the injected content resides entirely within a shortcode attribute string containing no HTML angle brackets, causing kses to pass it through unchanged at save time.
