EPSS Percentile
0th
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.
