CVE-2025-58686: Perfect Brands WooCommerce SQLi Flaw

CVE-2025-58686 Overview

CVE-2025-58686 is a SQL injection vulnerability in the Perfect Brands for WooCommerce WordPress plugin developed by quadlayers. The flaw affects all versions up to and including 3.6.2. Authenticated attackers with low privileges can inject malicious SQL statements through unsanitized inputs processed by the plugin. The vulnerability is classified under [CWE-89] (Improper Neutralization of Special Elements used in an SQL Command).

Critical Impact
An authenticated attacker can extract sensitive database contents from WordPress installations running the affected plugin, exposing customer data, credentials, and order information.

Affected Products

Perfect Brands for WooCommerce plugin (perfect-woocommerce-brands) versions up to and including 3.6.2

Technical Details for CVE-2025-58686

Vulnerability Analysis

The vulnerability stems from improper neutralization of special elements passed to SQL queries within the Perfect Brands for WooCommerce plugin. User-supplied input reaches database query construction without sufficient sanitization or parameterization. An attacker authenticated with at least low-level privileges can craft input that alters the structure of backend SQL statements.

The scope is marked as changed, meaning successful exploitation impacts resources beyond the vulnerable component. Confidentiality impact is high while availability impact is low. The attack requires network access and low complexity, with no user interaction needed beyond authentication.

The EPSS probability is 0.04%, reflecting a low predicted exploitation likelihood at this time. No public proof-of-concept exploit code has been published, and the vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog.

Root Cause

The root cause is the absence of proper parameterized queries or input escaping in the plugin's database access layer. Special characters such as single quotes, comments, and SQL operators pass through to the query parser without neutralization, allowing query manipulation.

Attack Vector

An authenticated user submits crafted parameters to plugin endpoints that interact with the WordPress database. Because the plugin concatenates user input into SQL queries without sanitization, the attacker can append UNION SELECT statements or boolean conditions to extract data. Refer to the Patchstack SQL Injection Advisory for technical details.

Detection Methods for CVE-2025-58686

Indicators of Compromise

Unusual SQL syntax such as UNION SELECT, SLEEP(, or comment sequences (--, #) appearing in HTTP request parameters targeting plugin endpoints
Unexpected database query errors in PHP or WordPress logs referencing the perfect-woocommerce-brands plugin
Outbound data transfers from the WordPress host following authenticated requests to plugin URLs
New or modified administrator accounts in the wp_users table without corresponding admin activity

Detection Strategies

Inspect web server access logs for query strings containing SQL metacharacters directed at plugin endpoints
Enable WordPress debug logging and review wp-content/debug.log for malformed queries originating from the plugin
Deploy a web application firewall rule set that flags SQL injection patterns against /wp-admin and plugin AJAX handlers

Monitoring Recommendations

Monitor authenticated session activity for low-privileged accounts performing high volumes of plugin-related requests
Alert on database query anomalies such as long-running queries or queries returning unusually large result sets
Track plugin version inventory across WordPress estates to identify unpatched installations of perfect-woocommerce-brands

How to Mitigate CVE-2025-58686

Immediate Actions Required

Update Perfect Brands for WooCommerce to a version later than 3.6.2 as soon as the vendor releases a fix
Audit WordPress user accounts and revoke unnecessary contributor, author, or shop-manager privileges
Review database logs for suspicious queries dating back to the plugin's installation
Rotate database credentials and WordPress secret keys if compromise is suspected

Patch Information

Review the Patchstack SQL Injection Advisory for vendor remediation guidance. Apply the patched plugin release from the WordPress plugin repository once available, and verify the installed version using the WordPress admin Plugins page.

Workarounds

Deactivate and remove the Perfect Brands for WooCommerce plugin until a patched version is installed
Restrict access to plugin endpoints using web server access controls or WAF rules targeting SQL injection signatures
Limit database user privileges so the WordPress database account cannot read sensitive tables outside its scope

bash

# Disable the vulnerable plugin via WP-CLI until patched
wp plugin deactivate perfect-woocommerce-brands
wp plugin delete perfect-woocommerce-brands

# After patch release, update to the fixed version
wp plugin update perfect-woocommerce-brands
