CVE-2026-57655Network attack vector

Unauthorized child-theme creation via missing form nonce

Published Jun 26, 2026 · Updated Jun 26, 2026

Cross-site request forgery in Child Theme Wizard 1.4 and earlier allows remote attackers to trigger unauthorized child-theme creation. The administrative creation form accepts state-changing submissions without validating a CSRF nonce, then writes a child theme for the selected parent theme. Exploitation requires a logged-in WordPress administrator to visit a crafted page or submit an attacker-controlled form, and the supported impact is unauthorized theme creation rather than code execution.
