Schema & Structured Data for WP & AMP - Security Vulnerability (CVE-2026-82127)

AI enriched 5 days ago (2026-10-02 09:12 UTC)

Technical Summary

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.

Potential Impact

Severity is LOW (CVSS 3.5). Depending on deployment context, affected components may be exposed to unauthorized actions or data integrity risk.

Exploitability Assessment

Exploitability is assessed as Low based on severity and technical exposure profile.

Primary risk drivers: severity and technical exposure profile

Mitigation Recommendations

Validate affected product versions, prioritize patching, and monitor references for vendor remediation guidance. If immediate patching is not possible, apply compensating controls and limit exposure of vulnerable surfaces.

Detection & Monitoring

Track authentication anomalies, unexpected file writes, and suspicious plugin API activity around affected components.

Business Impact Lens

AI risk score 30/100 (Low, Low) with priority P5 Monitor. Prioritize remediation where affected components process customer data, admin sessions, or Internet-exposed workflows.
