Vulnerability Overview

Vulnerability in wordpress plugin Membership Simplified v1.58, The code in membership-simplified-for-oap-members-only/updateDB.php is vulnerable to blind SQL injection because it doesn't sanitize user input via recordId in the delete_media function.

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-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')

Reaching this weakness in Membership Simplified < 1.58 takes a caller who can reach the endpoint. SQL injection happens when request data is concatenated into a query instead of being bound as a parameter, letting an attacker change the structure of the statement rather than just its values.

A working injection can read any table the database user can see, which on a WordPress install means user records, password hashes and session or API secrets stored in options. For Membership Simplified the fix is 1.58: builds < 1.58 are affected, anything from 1.58 onward is not.

Remediation

Update to version 1.58, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Membership Simplified: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Membership Simplified 1.58 closes this, and updating the plugin is the step that ends it.
