CVE-2022-1472 is a high-severity Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in the Better Find and Replace WordPress plugin, affecting versions < 1.3.6. 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 1.3.6; sites on affected versions should update now. Disclosed May 2022, reported by lucy.

Vulnerability Overview

The Better Find and Replace WordPress plugin before 1.3.6 does not properly sanitise, validate and escape various parameters before using them in an SQL statement, leading to an SQL Injection

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 Better Find and Replace < 1.3.6 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 Better Find and Replace the fix is 1.3.6: builds < 1.3.6 are affected, anything from 1.3.6 onward is not.

Remediation

Update to version 1.3.6, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Better Find and Replace: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Better Find and Replace 1.3.6 closes this, and updating the plugin is the step that ends it.
