Vulnerability Overview

Plugin Settings Update vulnerability in ShortPixel's ShortPixel Adaptive Images plugin <= 3.3.1 at WordPress allows an attacker with a low user role like a subscriber or higher to change the plugin settings.

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-284: Improper Access Control

Reaching this weakness in ShortPixel Adaptive Images <= 3.3.1 takes a caller who can reach the endpoint. Improper access control means the code decides what a caller may do using something other than their actual permissions, so the decision can be wrong without any check appearing to be missing.

Whoever can shape the request decides the answer, so the protected action runs for callers the code never meant to allow. For ShortPixel Adaptive Images the fix is 3.4.0: builds <= 3.3.1 are affected, anything from 3.4.0 onward is not.

Remediation

Update to version 3.4.0, 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: ShortPixel Adaptive Images 3.4.0 closes this, and updating the plugin is the step that ends it.
