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

SQL Injection vulnerability in the WP Travel Gutenberg Blocks WordPress plugin allows attackers to inject malicious SQL queries via unsanitized input. The blind SQL injection variant means attackers can extract data indirectly by observing application behavior differences. The vulnerability affects all versions through 3.9.4.

MitigationUpdate to the patched version of WP Travel Gutenberg Blocks when released. Until then, consider disabling the plugin or deploying a WAF rule to block SQL injection attempts.

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 WP Travel Gutenberg Blocks is installed
    Access WordPress admin dashboard, go to Plugins > Installed Plugins, and search for 'WP Travel Gutenberg Blocks' or check the /wp-content/plugins/ directory for the plugin folder
    Affected if The plugin is not found in the installed plugins list
  2. Check installed plugin version
    In WordPress admin > Plugins > Installed Plugins, click on the plugin name to view details, or inspect the main plugin file (e.g., wp-travel-gutenberg-blocks.php) for the 'Version' header comment
    Affected if Unable to determine version or version cannot be read
  3. Compare version to affected range
    Compare the installed version number to the affected range (versions through 3.9.4). Any version 3.9.4 or lower is within the affected range
    Affected if Installed version is 3.9.4 or lower
  4. Confirm plugin is active
    In WordPress admin > Plugins > Installed Plugins, verify the plugin status shows 'Active' under the plugin name
    Affected if Plugin is installed but not active (inactive plugins still present code but are not executable)
  5. Identify vulnerable input parameters
    Review server access logs for unusual SQL syntax in URL parameters, particularly in requests targeting plugin endpoints. Common SQL injection indicators include: UNION SELECT, OR 1=1, quotes followed by SQL keywords, or unexpected parentheses in query strings
    Affected if Suspicious SQL-like patterns found in logs targeting plugin-related URLs

The environment is affected if the WP Travel Gutenberg Blocks plugin is installed, active, and running version 3.9.4 or lower.
