CVE-2024-30434Network attack vector

Administrator-level stored script execution in Contact records

Published Mar 29, 2024 · Updated Apr 28, 2026

Stored XSS in the Contact component of WP-CRM System 3.2.9 and earlier allows remote authenticated users to run script in site visitors' browsers. The upstream changelog identifies the Contact component, but neither it nor the CNA record discloses which field reaches page output without context-appropriate neutralization. Administrator access is required to store the payload, and another user must view the affected Contact output before script runs in that site's origin.
