CVE-2026-79621: Unknown Catalogx

Medium severity, CVSS 4.3. EPSS: 0.1% chance of exploitation in the next 30 days.

The CatalogX WordPress plugin before 6.1.3 does not sanitise or escape content that an unauthenticated user can store before including it in the product enquiry notification email sent to the site administrator, allowing unauthenticated attackers to inject arbitrary content into that email, which is delivered when an unrelated visitor later submits a product enquiry.
