CVE-2026-82127

Schema & Structured Data for WP & AMP < 1.67 - Editor+ Stored XSS via Taxonomy Term Fields

The Schema & Structured Data for WP & AMP WordPress plugin before 1.67 does not perform a capability check when saving several of its fields, nor escape them when outputting them back, allowing users with the editor role and above to inject arbitrary web scripts that execute when a higher privileged user views the affected screen. This is only exploitable on multisite installs, where editors do not hold the unfiltered_html capability.
