CVE-2025-12118: Kevingillispie Schema Scalpel

Medium severity, CVSS 6.4. EPSS: 0.2% chance of exploitation in the next 30 days.

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.
