At a glance

CVE-2026-86809 is a medium-severity Insufficient Verification of Data Authenticity vulnerability in the المنتور فارسی WordPress plugin, affecting versions 2.7.10 – 2.8.1. It carries a CVSS score of 5.3 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 2.8.2; sites on affected versions should update now. Disclosed September 2026, reported by Artus KG.

Vulnerability Overview

The المنتور فارسی plugin for WordPress is vulnerable to Payment Bypass in versions 2.7.10 through 2.8.1. This is due to missing validation that the Authority parameter returned by the ZarinPal gateway callback matches the authority stored for the transaction being completed. This makes it possible for unauthenticated attackers to complete a pending order without paying for it by supplying a valid ZarinPal payment authority obtained from a different transaction.

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 privileges on the target site, and no interaction from a victim user.

CWE-345: Insufficient Verification of Data Authenticity

The product does not sufficiently verify the origin or authenticity of data, in a way that causes it to accept invalid data.

Remediation

Update to version 2.8.2, or a newer patched version

How does WordSec protect against this?

This one needs no account at all, which puts it outside what login hardening can reach; WordSec's login security narrows the account-level paths around it, and the firewall is what inspects the request itself. None of that substitutes for the fix: المنتور فارسی 2.8.2 closes this, and updating the plugin is the step that ends it.
