CVE-2025-4964: wp online users stats vulnerability

What is known

The WP Online Users Stats plugin for WordPress is vulnerable to time-based SQL Injection via the ‘table_name’ parameter in all versions up to, and including, 1.0.0 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 Editor-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

Business impact

Successful exploitation of CVE-2025-4964, a medium vulnerability (CVSS 4.9) affecting wp online users stats, may affect the confidentiality, integrity or availability of the vulnerable environment. The exact impact depends on the installed version, exposed interfaces and deployment configuration.

Recommended administrator action

Confirm whether wp online users stats is present and compare installed versions with the vendor advisory and NVD record. Apply the vendor patch or documented mitigation; until remediation is complete, reduce exposure of affected interfaces, review relevant logs and monitor for indicators of exploitation. DataHouse can support version verification, managed patching, network exposure reduction, log review and backup validation for dedicated, cloud and colocated environments.
