At a glance

CVE-2026-93580 is a medium-severity Missing Authorization vulnerability in the InPost PL WordPress plugin, affecting versions 1.7.5 – 1.9.7. 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 1.9.8; sites on affected versions should update now. Disclosed September 2026, reported by Ryan Fabella.

Vulnerability Overview

The InPost for WooCommerce plugin for WordPress is vulnerable to unauthorized access in versions 1.7.5 through 1.9.7. This is due to a missing capability check on a function. This makes it possible for unauthenticated attackers to perform an unauthorized action.

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-862: Missing Authorization

Reaching this weakness in InPost PL 1.7.5 – 1.9.7 takes a caller who can reach the endpoint. 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 InPost PL the fix is 1.9.8: builds 1.7.5 – 1.9.7 are affected, anything from 1.9.8 onward is not.

Remediation

Update to version 1.9.8, 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: InPost PL 1.9.8 closes this, and updating the plugin is the step that ends it.
