CVE-2026-3334
At a glance
CVE-2026-3334 is a high-severity Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in the CMS Commander WordPress plugin, affecting versions <= 2.288. It carries a CVSS score of 8.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires an authenticated account at Custom level or above. No fixed release has been reported yet; treat installations running this software as exposed. Disclosed March 2026, reported by chaeyp.
Vulnerability Overview
The CMS Commander plugin for WordPress is vulnerable to SQL Injection via the 'or_blogname', 'or_blogdescription', and 'or_admin_email' parameters in all versions up to, and including, 2.288. This is due to insufficient escaping on the user supplied parameters and lack of sufficient preparation on the existing SQL queries in the restore workflow. This makes it possible for authenticated attackers, with CMS Commander API key access, 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, integrity, availability — full site compromise territory.
CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
CMS Commander <= 2.288 carries this weakness at or_blogname, and reaching it takes an account at Custom 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. No fixed build of this plugin is recorded for CMS Commander yet, so installs running <= 2.288 stay exposed until the vendor ships one.
Remediation
No known patch available. Please review the vulnerability's details in depth and employ mitigations based on your organization's risk tolerance. It may be best to uninstall the affected software and find a replacement.
How does WordSec protect against this?
An attacker needs Custom 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. No patched version is recorded yet, which is the case where a filtering layer matters most, because there is nothing to update to.
