CVE-2026-15650
The RT Mega Menu – Mega Menu Builder for Elementor & Gutenberg plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'pointer_menu_item' Block Attribute in all versions up to, and including, 1.5.2 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. The payload bypasses wp_kses_post filtering applied to post content on save because it contains no HTML tags and survives intact inside the block comment's JSON attributes, reaching the walker unescaped at render time.
