What the vulnerability does
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.
Explanation of Vulnerability in Simple Terms

An attacker with a low-privilege account can alter or tamper with notes belonging to other users or posts. The vulnerability requires an active user account but no special interaction from victims.
What an attacker can do
Modify or tamper with notes created by other users on posts and pages.
Potential impact on your site
Users' private notes can be altered or deleted by other authenticated users, compromising data integrity and privacy.
Conditions required to exploit
Attacker must have a valid user account with at least low-level privileges on the site.
