Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

A blind SQL injection vulnerability exists in the TaxoPress (simple-tags) WordPress plugin through version 3.44.0. The vulnerability stems from improper neutralization of special elements in SQL commands, allowing authenticated attackers to inject malicious SQL queries.

MitigationUpdate TaxoPress to the latest patched version. If no update is available, disable the plugin until a fix is released. Alternatively, implement input validation and use prepared statements for all database queries.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Verify TaxoPress plugin is installed
    Navigate to WordPress admin > Plugins and look for 'TaxoPress' or 'Simple Tags' in the installed plugins list, or use WP-CLI: wp plugin list --name=simple-tags
    Affected if TaxoPress or Simple Tags appears in the installed plugins list
  2. Check the installed TaxoPress version
    In WordPress admin > Plugins > TaxoPress, view the plugin details to see the version number, or use WP-CLI: wp plugin get simple-tags --field=version
    Affected if The displayed version is 3.44.0 or lower (any version through 3.44.0 is affected)
  3. Confirm the plugin is active
    In WordPress admin > Plugins, verify that TaxoPress shows as 'Active', or use WP-CLI: wp plugin status simple-tags
    Affected if The plugin status shows as 'Active' (the vulnerability is exploitable when the plugin is enabled)
  4. Audit user access to TaxoPress
    Review WordPress user roles and capabilities to determine if untrusted users have access to TaxoPress functionality (the vulnerability requires authentication to exploit)
    Affected if Users with lower-privilege accounts (subscriber, contributor, or custom roles) can access TaxoPress features

If TaxoPress or Simple Tags is installed, active, and the version is 3.44.0 or lower, the environment is vulnerable to the blind SQL injection described in CVE-2026-42646.
