At a glance

This record tracks a high-severity Improper Input Validation vulnerability in the Indeed Membership Pro WordPress plugin, affecting versions <= 7.5. It carries a CVSS score of 8.3 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 7.6; sites on affected versions should update now. Disclosed February 2019, reported by James Fraser.

Vulnerability Overview

The Indeed Membership Pro plugin for WordPress is vulnerable to Remote File Inclusion in versions up to, and including, 7.5 via the imgUrl feature. This allows unauthorized attackers to include remote files on the server, resulting in code execution.

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-20: Improper Input Validation

Reaching this weakness in Indeed Membership Pro <= 7.5 takes a caller who can reach the endpoint. Improper input validation means the application accepts input without confirming it has the form, type or range the code downstream assumes.

The concrete impact depends on where the unvalidated value lands, which is why records in this class range from cosmetic bugs to full compromise. For Indeed Membership Pro the fix is 7.6: builds <= 7.5 are affected, anything from 7.6 onward is not.

Remediation

Update to version 7.6, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Indeed Membership Pro: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Indeed Membership Pro 7.6 closes this, and updating the plugin is the step that ends it.
