At a glance

CVE-2026-7559 is a medium-severity Missing Authorization vulnerability in the Affilia WordPress plugin, affecting versions <= 3.3.3. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). Exploitation requires an authenticated account at Subscriber level or above. The issue is fixed in version 3.3.4; sites on affected versions should update now. Disclosed July 2026, reported by loris4py.

Vulnerability Overview

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.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no interaction from a victim user.

CWE-862: Missing Authorization

Reaching this weakness in Affilia <= 3.3.3 takes an account at Subscriber level or above. A missing authorization check means a function is reachable by anyone who can reach the endpoint, because the code never asks whether the caller is allowed to perform the action.

Any user who can reach the endpoint gets to run an action reserved for higher-privileged roles, from reading protected data to changing settings or content. For Affilia the fix is 3.3.4: builds <= 3.3.3 are affected, anything from 3.3.4 onward is not.

Remediation

Update to version 3.3.4, or a newer patched version

How does WordSec protect against this?

Because it turns on account access, WordSec's login security is the relevant layer: role-based two-factor, captcha and brute-force limits raise the cost of getting the account this needs. None of that substitutes for the fix: Affilia 3.3.4 closes this, and updating the plugin is the step that ends it.
