description

Email Customizer for WooCommerce (Pro) for WordPress through version 3.9.5 is affected. An authenticated user with subscriber-level access or higher can execute code on the web server, potentially compromising the site. Exploitation requires a valid account with at least subscriber privileges.

mitigation

Update to a vendor release later than 3.9.5 when one is available; no fixed version is recorded. Until then, deactivate the plugin or restrict subscriber and higher-level accounts to trusted users.
