Summary

The All-In-One Security (AIOS) WordPress plugin before 5.1.5 does not limit what log files to display in it's settings pages, allowing an authorized user (admin+) to view the contents of arbitrary files and list directories anywhere on the server (to which the web server has access). The plugin only displays the last 50 lines of the file.
