Unauthorized Access in Affilia WordPress Plugin

Publication date: 2026-07-11

Last updated on: 2026-07-11

Assigner: Wordfence

Description
The Affilia – Affiliate Program & Referral Tracking for WordPress plugin for WordPress is vulnerable to unauthorized access in all versions up to, and including, 3.3.3. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with subscriber-level access and above, to approve or reject affiliate referrals, credit commissions to affiliate wallets, delete referral records, and modify custom banner plugin options, enabling financial fraud. The nonce required to pass the only authentication check is embedded in every frontend page load via rtwalwm_global_params.rtwalwm_nonce, making it trivially accessible to any authenticated user regardless of role.
