Check Plagiarism <= 2.0 - Missing Authorization to Authenticated (Subscriber+) Settings Update

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.

Caphyon Ltd Advanced Installer 19.3 and earlier and many products that use the updater from Advanced Installer (Advanced Updater) are affected by a remote code execution vulnerability via the CustomDetection parameter in the update check function. To exploit this vulnerability, a user must start an affected installation to trigger the update check.
