At a glance

CVE-2021-24748 is a high-severity Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in the Email Before Download WordPress plugin, affecting versions <= 6.7. It carries a CVSS score of 7.2 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). The issue is fixed in version 6.8; sites on affected versions should update now. Disclosed November 2021, reported by bl4derunner.

Vulnerability Overview

The Email Before Download WordPress plugin before 6.8 does not properly validate and escape the order and orderby GET parameters before using them in SQL statements, leading to authenticated SQL injection issues

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, integrity, availability — full site compromise territory.

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

Reaching this weakness in Email Before Download <= 6.7 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 Email Before Download the fix is 6.8: builds <= 6.7 are affected, anything from 6.8 onward is not.

Remediation

Update to version 6.8, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Email Before Download: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Email Before Download 6.8 closes this, and updating the plugin is the step that ends it.
