WordPress Infinite Scroll – Ajax Load More <= 5.5.3 - Directory Traversal

The WordPress Infinite Scroll – Ajax Load More plugin for WordPress is vulnerable to Directory Traversal in versions up to, and including, 5.5.3 via the 'type' parameter found in the alm_get_layout() function. This makes it possible for authenticated attackers, with administrative permissions, to read the contents of arbitrary files on the server, which can contain sensitive information.
