 "title": "SchemaEngine AI – AI Schema Markup, Reviews & Rich Snippets for SEO <= 3.1.3 - Authenticated (Contributor+) Stored Cross-Site Scripting via JSON-LD Structured Data",
 "description": "The review-schema plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the JSON-LD structured data output in all versions up to, and including, 3.1.3. This is due to the schema graph being printed inside a script element with wp_json_encode() using JSON_UNESCAPED_SLASHES and no escaping of HTML tags, while values such as the WebPage description are HTML-entity-decoded from the post excerpt or content, so an entity-encoded '</script>' sequence in post content ends the script element. 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.",
