PostBox < 1.0.5 - Missing Authorization to Authenticated (Subscriber+) Log Export

Description

The WP Email Log – PostBox plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on the pbeml_get_log_data() function in all versions up to, and including, 1.0.4. This makes it possible for authenticated attackers, with Subscriber-level access and above, to export and retrieve log data.
