AMP for WP < 1.0.93.2 - Authenticated(Contributor+) Arbitrary Post Deletion via amppb_remove_saved_layout_data

Description

The AMP for WP – Accelerated Mobile Pages plugin for WordPress is vulnerable to unauthorized loss of data due to a missing capability check on the 'amppb_remove_saved_layout_data' function in all versions up to, and including, 1.0.93.1. This makes it possible for authenticated attackers, with contributor access and above, to delete arbitrary posts on the site.
