Arbitrary zero-argument PHP function invocation in the Youtube Showcase (Video Gallery - YouTube Gallery, Playlist & Video Grid) plugin for WordPress affects all versions up to and including 4.0.3, letting authenticated Subscriber-level users abuse the emd_delete_file() AJAX handler to call any callable PHP function name with no arguments. Because the handler validates only a nonce and omits a current_user_can() capability check, low-privileged accounts can trigger functions such as phpinfo(), get_defined_vars(), or error_get_last() to disclose sensitive server and application data. No public exploit identified at time of analysis and the issue is not in CISA KEV, so risk is currently theoretical but credible given the low privilege bar.
