CVE-2025-12118
Full vulnerability record from the local CVENow database.
Description
The Schema Scalpel plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the post title in all versions up to, and including, 1.6.1 due to insufficient input sanitization and output escaping when outputting user-supplied data into JSON-LD schema markup. 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.

Esto hace posible que atacantes autenticados, con acceso de nivel de Colaborador y superior, inyecten scripts web arbitrarios en páginas que se ejecutarán cada vez que un usuario acceda a una página inyectada."
