The easy-wp-smtp plugin before 1.4.4 for WordPress allows Administrator account takeover, as exploited in the wild in December 2020. If an attacker can list the wp-content/plugins/easy-wp-smtp/ directory, then they can discover a log file (such as #############_debug_log.txt) that contains all password-reset links. The attacker can request a reset of the Administrator password and then use a link found there.

** DISPUTED ** Laminas Project laminas-http before 2.14.2, and Zend Framework 3.0.0, has a deserialization vulnerability that can lead to remote code execution if the content is controllable, related to the __destruct method of the Zend\Http\Response\Stream class in Stream.php. NOTE: Zend Framework is no longer supported by the maintainer. NOTE: the laminas-http vendor considers this a "vulnerability in the PHP language itself" but has added certain type checking as a way to prevent exploitation in (unrecommended) use cases where attacker-supplied data can be deserialized.
