CVE-2026-95522: Easy Digital Downloads SQL Injection Flaw

CVE-2026-95522 Overview

CVE-2026-95522 is a SQL Injection vulnerability [CWE-89] affecting the Easy Digital Downloads WordPress plugin in versions up to and including 3.7.0. The flaw allows authenticated users holding the Shop Manager role to inject arbitrary SQL statements into database queries executed by the plugin. Successful exploitation can lead to unauthorized disclosure of database contents and partial impact on availability. The vulnerability is scoped as changed, meaning exploitation can affect resources beyond the vulnerable component itself. The issue was published to the National Vulnerability Database (NVD) on 2026-09-23 and is tracked by Patchstack.

Critical Impact
An authenticated Shop Manager can execute arbitrary SQL queries against the WordPress database, exposing customer records, order data, and sensitive site configuration.

Affected Products

Easy Digital Downloads plugin for WordPress, versions <= 3.7.0
WordPress sites operating the vulnerable plugin with Shop Manager accounts provisioned
E-commerce deployments relying on Easy Digital Downloads for digital product sales

Technical Details for CVE-2026-95522

Vulnerability Analysis

The vulnerability resides in Easy Digital Downloads code paths that accept input from privileged Shop Manager users and pass that input into SQL queries without adequate sanitization or parameterization. Because the plugin trusts the elevated role, input validation on affected endpoints is insufficient to prevent query manipulation. An attacker with Shop Manager credentials can alter query structure to read arbitrary tables, including wp_users, order history, and plugin configuration. The scope change indicated by the vulnerability metrics reflects that a successful injection can reach data owned by other components within the WordPress environment.

Root Cause

The root cause is improper neutralization of special elements used in a SQL command [CWE-89]. Input supplied through affected Shop Manager workflows is concatenated into SQL statements rather than bound as parameters via WordPress database abstraction methods such as $wpdb->prepare(). This omission allows syntactically valid injections to be interpreted as query logic.

Attack Vector

Exploitation requires network access to the WordPress administrative interface and valid Shop Manager credentials. The attacker submits crafted parameters through plugin-managed forms or request endpoints, injecting SQL fragments that the plugin appends to database queries. No user interaction from other administrators is required. Refer to the Patchstack Vulnerability Report for endpoint-specific details.

No verified public proof-of-concept code is available. The vulnerability mechanism follows the standard pattern of unsanitized input reaching a database query builder in a privileged plugin workflow.

Detection Methods for CVE-2026-95522

Indicators of Compromise

Unexpected SQL syntax fragments such as UNION SELECT, SLEEP(, INFORMATION_SCHEMA, or comment sequences appearing in HTTP request parameters directed at Easy Digital Downloads endpoints
Database error entries in PHP or MySQL logs correlating with authenticated Shop Manager sessions
Unusual read volume against wp_users, wp_usermeta, or Easy Digital Downloads order tables originating from web application processes

Detection Strategies

Enable WordPress and web server request logging for all /wp-admin/ routes serviced by the plugin and inspect parameter payloads for SQL metacharacters
Deploy a web application firewall (WAF) ruleset that inspects authenticated POST bodies for SQL injection patterns rather than only anonymous traffic
Correlate Shop Manager login events with subsequent database query anomalies to surface credential misuse

Monitoring Recommendations

Alert on newly created or elevated Shop Manager accounts across managed WordPress sites
Monitor outbound traffic from the web host for signs of database exfiltration following administrative sessions
Track plugin version inventory continuously to identify hosts still running Easy Digital Downloads <= 3.7.0

How to Mitigate CVE-2026-95522

Immediate Actions Required

Upgrade Easy Digital Downloads to a version later than 3.7.0 as identified in the Patchstack Vulnerability Report
Audit all accounts holding the Shop Manager role and remove unnecessary assignments
Rotate credentials for existing Shop Manager accounts and enforce multi-factor authentication on WordPress administrative logins

Patch Information

The vendor has released a fixed version of the Easy Digital Downloads plugin. Site administrators should apply the update through the WordPress plugin manager or by deploying the patched release from the official WordPress plugin repository. Confirm the installed version reports a release higher than 3.7.0 after upgrade.

Workarounds

Restrict access to WordPress administrative endpoints using IP allow-listing at the reverse proxy or WAF layer
Temporarily downgrade Shop Manager accounts to a lower-privilege role until patching is complete
Enable a WAF signature set targeting SQL injection patterns on authenticated administrative traffic

bash

# Verify installed Easy Digital Downloads version using WP-CLI
wp plugin get easy-digital-downloads --field=version

# Update the plugin to the patched release
wp plugin update easy-digital-downloads

# List users assigned the Shop Manager role for review
wp user list --role=shop_manager --fields=ID,user_login,user_email,user_registered
