This is due to insufficient validation of the &#8216;path&#8217; parameter in the emd_delete_file() AJAX handler in includes\/common-functions.php. The user-supplied value is passed through sanitize_text_field(), has its trailing &#8216;_PLUGIN_DIR&#8217; substring stripped, and is then invoked as a PHP function name with no arguments via `$sess_name()`. The handler is gated only by a nonce \u2014 no current_user_can() check is present \u2014 and the nonce is emitted on any front-end page that renders a form shortcode containing file fields. This makes it possible for authenticated attackers, with Subscriber-level access and above, to invoke arbitrary zero-argument PHP functions (such as phpinfo, phpversion, get_defined_vars, error_get_last), resulting in sensitive information disclosure and potential further compromise depending on the functions available in the environment.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The Youtube Showcase plugin for WordPress is vulnerable to Arbitrary Function Call in versions up to and including 4.0.3.
