Remote code execution in the Hummingbird performance/caching plugin for WordPress (versions up to and including 3.21.0) lets unauthenticated attackers write arbitrary PHP into a web-accessible debug-log file and execute it with a single anonymous request. The plugin's protective '<?php die(); ?>' header is silently dropped due to a PHP namespace bug in a class_exists() check, and unsanitized cookie names are written straight into wp-content/wphb-logs/page-caching-log.php. Reported by Wordfence with no public exploit identified at time of analysis; exploitation depends on a non-default Debug Log configuration.
