The WC Affiliate – A Complete WooCommerce Affiliate Plugin plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on the 'export_all_data' function in all versions up to, and including, 2.5.3. This makes it possible for authenticated attackers, with Subscriber-level access and above, to expose sensitive affiliate data, including personally identifiable information (PII).
