Page & Post Notes <= 1.3.4 - Missing Authorization to Authenticated (Subscriber+) Note Update/Deletion

The Page & Post Notes plugin for WordPress is vulnerable to unauthorized modification of notes due to a missing capability check on the 'yydev_notes_save_dashboard_data' function in all versions up to, and including, 1.3.4. This makes it possible for authenticated attackers, with Subscriber-level access and above, to modify notes.
