WP Project Manager <= 2.6.17 - Missing Authorization to Authenticated (Subscriber+) Limited Arbitrary Options Update

The WP Project Manager – Task, team, and project management plugin featuring kanban board and gantt charts plugin for WordPress is vulnerable to unauthorized loss of data due to a missing capability check in the '/pm/v2/settings/notice' endpoint all versions up to, and including, 2.6.17. This makes it possible for authenticated attackers, with Subscriber-level access and above, to cause a persistent denial of service condition.
