CVE-2026-9019
The Easy Image Collage plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'grid[properties][borderColor]' and 'grid[images][N][attachment_url]' Parameters in all versions up to, and including, 1.13.6 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Because the data is stored via update_post_meta() rather than wp_insert_post() post content, WordPress's unfiltered_html restriction does not apply, meaning Authors cannot be blocked from this attack path by capability controls alone.

Esto hace posible que atacantes autenticados, con acceso de nivel de autor y superior, inyecten scripts web arbitrarios en páginas que se ejecutarán cada vez que un usuario acceda a una página inyectada. Debido a que los datos se almacenan a través de update_post_meta() en lugar del contenido de la publicación de wp_insert_post(), la restricción unfiltered_html de WordPress no se aplica, lo que significa que los autores no pueden ser bloqueados de esta ruta de ataque solo con controles de capacidad."
