CVE-2026-57777
At a glance
CVE-2026-57777 is a medium-severity Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in the WooCommerce WordPress plugin, affecting versions <= 10.9.4. It carries a CVSS score of 4.9 (reachable over the network; low attack complexity; high confidentiality impact). Exploitation requires an authenticated account at Shop Manager level or above. The issue is fixed in version 11.0; sites on affected versions should update now. Disclosed September 2026, reported by Ananda Dhakal.
Vulnerability Overview
The WooCommerce plugin for WordPress is vulnerable to SQL Injection in all versions up to, and including, 10.9.4. This is due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with shop manager-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
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.
CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
Reaching this weakness in WooCommerce <= 10.9.4 takes an account at Shop Manager level or above. 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 WooCommerce the fix is 11.0: builds <= 10.9.4 are affected, anything from 11.0 onward is not.
Remediation
Update to version 11.0, or a newer patched version
How does WordSec protect against this?
An attacker needs Shop Manager access first, so the firewall sees the attempt as traffic from a logged-in account: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: WooCommerce 11.0 closes this, and updating the plugin is the step that ends it.
