Impact
The WPCOM Member plugin for WordPress allows an authenticated user with Contributor-level access or higher to trigger a local file inclusion through the action parameter in a shortcode. This flaw enables the attacker to include and execute arbitrary .php files on the server, providing full code-execution capabilities, bypassing access controls, and exposing sensitive data.
Affected Systems
WordPress sites that have installed the WPCOM Member plugin version 1.7.14 or earlier are affected. Any deployment running a vulnerable version is at risk until it is upgraded. Versions newer than 1.7.14 are considered fixed.
Risk and Exploitability
The CVSS score of 8.8 denotes high severity, yet the EPSS score of less than 1% indicates exploitation opportunities are currently low. The vulnerability is not listed in the CISA KEV catalog, but the impact—full code execution on the host—remains devastating. An attacker with Contributor access can manipulate the shortcode to reference any local .php file, such as uploaded content or core files, achieving remote code execution with minimal effort.
