What the vulnerability does
The Check Plagiarism plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the chk_plag_mine_plugin_wpse10500_admin_action() function in all versions up to, and including, 2.0. This makes it possible for authenticated attackers, with Subscriber-level access and above, to update the API key.
Explanation of Vulnerability in Simple Terms
Check Plagiarism versions 2.0 and earlier lack proper authorization checks, allowing authenticated users to modify data they should not have access to. An attacker with a low-privilege account can alter content without proper permission validation. The vulnerability requires login credentials but does not require user interaction beyond normal API calls.
What an attacker can do
Modify data or content without proper authorization as an authenticated user.
Potential impact on your site
Unauthorized data modification by authenticated users; integrity of plagiarism check records at risk.
Conditions required to exploit
Attacker must have a valid low-privilege account on the system.
