CVE-2025-39570Network attack vector

Authenticated PHP code execution via shortcode file parameter

Published Apr 16, 2025 · Updated May 12, 2026

Local file inclusion in the WPCOM Member plugin 1.7.7 and earlier allows remote authenticated users to execute server-side PHP code. The wpcom-member shortcode preserves an attacker-controlled file parameter and passes it into the template inclusion path without restricting the resolved filename. Contributor-level access is required, and code execution requires an includable local file, such as an uploaded image containing PHP.
