At a glance

CVE-2026-1883 is a medium-severity Authorization Bypass Through User-Controlled Key vulnerability in the Wicked Folders WordPress plugin, affecting versions <= 4.1.0. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). Exploitation requires an authenticated account at Contributor level or above. The issue is fixed in version 4.1.1; sites on affected versions should update now. Disclosed March 2026, reported by Youssef Elouaer.

Vulnerability Overview

The Wicked Folders – Folder Organizer for Pages, Posts, and Custom Post Types plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 4.1.0 via the delete_folders() function due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with Contributor-level access and above, to delete arbitrary folders created by other users.

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-639: Authorization Bypass Through User-Controlled Key

Wicked Folders <= 4.1.0 carries this weakness at delete_folders(), and reaching it takes an account at Contributor level or above. Authorization bypass through a user-controlled key, often called insecure direct object reference, means the application looks up a record by an identifier from the request without checking that the caller owns it.

Changing a number in the request is enough to read or modify other users' records, which on commerce and membership sites means customer data. For Wicked Folders the fix is 4.1.1: builds <= 4.1.0 are affected, anything from 4.1.1 onward is not.

Remediation

Update to version 4.1.1, 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: Wicked Folders 4.1.1 closes this, and updating the plugin is the step that ends it.
