Am I affected?

With a domain, we read the version its public headers and pages expose. A distribution build can carry the fix under an older number.

Description

The CourseCure Courses plugin for WordPress is vulnerable to Privilege Escalation in versions up to, and including, 1.5.1. This is due to a missing capability check in the ajax_save_settings() function, which accepts arbitrary POST parameters and calls update_option() with attacker-controlled keys and values without any authorization verification. This makes it possible for authenticated attackers, with subscriber-level access and above, to elevate their privileges to administrator by setting the default_role WordPress option to 'administrator' and users_can_register to '1', then registering a new account that is automatically granted full administrator access.
