Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in hiecor HieCOR Payment Gateway Plugin hcv4-payment-gateway allows SQL Injection.This issue affects HieCOR Payment Gateway Plugin: from n/a through <= 1.5.11.

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 HieCOR Payment Gateway Plugin (hcv4-payment-gateway) version <= 1.5.11 allows attackers to inject malicious SQL queries through unsanitized user input, potentially enabling unauthorized data access, modification, or disclosure of sensitive payment information stored in the database.

MitigationUpdate to the latest patched version of the HieCOR Payment Gateway Plugin immediately; if no patch exists, implement parameterized queries/prepared statements for all database operations and add input validation on all user-supplied parameters.

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. Locate the HieCOR Payment Gateway Plugin installation
    Check your WordPress plugins directory for a folder named 'hcv4-payment-gateway' or search for files containing 'hiecor' and 'payment-gateway' in the plugin path
    Affected if The plugin folder 'hcv4-payment-gateway' exists in the plugins directory
  2. Identify the installed plugin version
    Open the main plugin file (usually index.php or the primary PHP file in the plugin folder) and locate the version declaration in the plugin header comment, or check the readme.txt file for the 'Stable tag' or 'Version' entry
    Affected if The version number displayed is 1.5.11 or lower
  3. Confirm the plugin is active
    Log into the WordPress admin dashboard and navigate to Plugins > Installed Plugins; verify that 'HieCOR Payment Gateway' shows as 'Active'
    Affected if The plugin status shows as Active in the WordPress admin plugin list
  4. Verify database query handling
    Examine the plugin PHP files for direct SQL query construction using variables from $_POST, $_GET, or $_REQUEST without prepared statements or parameter binding; search for patterns like '$wpdb->query', 'mysqli_query', or PDO query methods where user input is concatenated directly into SQL strings
    Affected if Database query code accepts user-supplied input from request parameters without using parameterized queries or input sanitization functions

A user is affected if the HieCOR Payment Gateway Plugin (hcv4-payment-gateway) is installed, active, and running version 1.5.11 or earlier, with database query code that passes unsanitized user input directly into SQL statements.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Update to the latest patched version of the HieCOR Payment Gateway Plugin immediately; if no patch exists, implement parameterized queries/prepared statements for all database operations and add input validation on all user-supplied parameters.

Recommended fix Moderate confidence

latest available version of HieCOR Payment Gateway Plugin (newer than 1.5.11)

  1. Update the HieCOR Payment Gateway Plugin to the latest available version immediately to remediate the SQL injection vulnerability
  2. If automatic updates are not enabled, navigate to Plugins > Installed Plugins > HieCOR Payment Gateway and click Update Now
  3. After updating, verify the plugin is functioning correctly and test payment workflows
  4. Review any plugin changelog or security advisories from the vendor for details on what was fixed
  5. Consider implementing additional web application firewall (WAF) rules as a temporary protective measure if immediate update is not possible
