CVE-2026-3350
The Image Alt Text Manager plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the post title in all versions up to, and including, 1.8.2. This is due to insufficient input sanitization and output escaping when dynamically generating image alt and title attributes using a DOM parser. 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.

"value": "El plugin Image Alt Text Manager para WordPress es vulnerable a Cross-Site Scripting Almacenado a través del título de la publicación en todas las versiones hasta la 1.8.2, inclusive. Esto se debe a una sanitización de entrada y un escape de salida insuficientes al generar dinámicamente atributos 'alt' y 'title' de imagen utilizando un analizador DOM. Esto hace posible que atacantes autenticados, con acceso de nivel Autor o superior, inyecten scripts web arbitrarios en páginas que se ejecutarán cada vez que un usuario acceda a una página inyectada."
