## Description

The PayHere Payment Gateway plugin for WordPress is vulnerable to unauthorized modification of data via the payhere_capture AJAX action (capture_payment() function) in all versions up to, and including, 2.4.5, due to a missing capability check and missing nonce validation. This makes it possible for authenticated attackers, with Subscriber-level access and above, to capture authorized (held) PayHere payments for arbitrary orders, an action meant only for store managers.
