At a glance

CVE-2024-4390 is a medium-severity Incorrect Authorization vulnerability in the Depicter WordPress plugin, affecting versions <= 3.0.2. It carries a CVSS score of 6.5 (reachable over the network; low attack complexity; high confidentiality impact). Exploitation requires an authenticated account at Contributor level or above. The issue is fixed in version 3.1.0; sites on affected versions should update now. Disclosed June 2024, reported by Arkadiusz Hydzik.

Vulnerability Overview

The Slider and Carousel slider by Depicter plugin for WordPress is vulnerable to Arbitrary Nonce Generation in all versions up to, and including, 3.0.2. This makes it possible for authenticated attackers with contributor access and above, to generate a valid nonce for any WordPress action/function. This could be used to invoke functionality that is protected only by nonce checks.

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.

CWE-863: Incorrect Authorization

Reaching this weakness in Depicter <= 3.0.2 takes an account at Contributor level or above. Incorrect authorization means a permission check exists but evaluates the wrong thing, so it passes for callers it was meant to stop.

The action runs for users the code intended to exclude, with the same effect as having no check at all. For Depicter the fix is 3.1.0: builds <= 3.0.2 are affected, anything from 3.1.0 onward is not.

Remediation

Update to version 3.1.0, 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: Depicter 3.1.0 closes this, and updating the plugin is the step that ends it.
