At a glance
CVE-2026-27541 is a high-severity Improper Privilege Management vulnerability in the Wholesale Suite WordPress plugin, affecting versions <= 2.2.6. It carries a CVSS score of 7.2 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact).

Disclosed February 2026, reported by Teemu Saarentaus.
Vulnerability Overview
The Wholesale Suite – B2B, Dynamic Pricing & WooCommerce Wholesale Prices plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 2.2.6.This makes it possible for authenticated attackers, with Shop Manager-level access and above, to elevate their privileges to that of an administrator.
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. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.
CWE-269: Improper Privilege Management
Reaching this weakness in Wholesale Suite <= 2.2.6 takes an account at Shop Manager level or above. Improper privilege management means the code lets an account end up with capabilities its role should not have.
It converts a low-privileged account into an administrative one, which makes every other restriction on the site irrelevant. For Wholesale Suite the fix is 2.2.7: builds <= 2.2.6 are affected, anything from 2.2.7 onward is not.
Remediation
Update to version 2.2.7, 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: Wholesale Suite 2.2.7 closes this, and updating the plugin is the step that ends it.
