Description
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.

AI Analysis

Impact

The plugin contains a time‑based SQL injection flaw in the table_name parameter. Insufficient escaping combined with lack of prepared statements lets an editor or higher role append arbitrary SQL to existing queries, enabling extraction of sensitive database content.

Affected Systems

WordPress sites using the WP Online Users Stats plugin by hk1993, versions 1.0.0 and earlier.

Risk and Exploitability

The CVSS score of 4.9 reflects moderate severity, and the EPSS score of less than 1% indicates a very low probability of exploitation in the wild. The vulnerability is not listed in the CISA KEV catalog. Exploitation requires authenticated access with Editor privileges or higher, which is common on many WordPress installations. Once compromised, attackers can read arbitrary tables through the injected queries.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Upgrade WP Online Users Stats to a version newer than 1.0.0.
  • If an upgrade is not immediately available, remove or disable the table_name parameter from public access or apply a code patch to fully escape its value using parameterized queries.
  • Audit user roles to ensure only trusted accounts have Editor or higher privileges, and consider restricting such privileges on production sites.
