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 HiStudy (Education WordPress Theme) allows attackers to inject malicious SQL commands via unsanitized user inputs, potentially enabling data exfiltration, privilege escalation, or complete database compromise.

MitigationUpdate HiStudy theme to version 3.1.0 or later to obtain the patched version with proper input sanitization.

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 HiStudy theme version in WordPress
    In WordPress admin dashboard, go to Appearance > Themes and locate the HiStudy theme. Click on the theme to view its details, which typically display the version number. Alternatively, check the style.css file in the theme directory (wp-content/themes/histudy/style.css) for the 'Version:' comment header.
    Affected if The displayed version is below 3.1.0 or no version is listed and the theme appears to be an older release of HiStudy.
  2. Compare installed version against fixed release
    Review the discovered version number from step 1 and compare it to the patched version 3.1.0. Ensure you are comparing the complete version string (e.g., 3.0.5, 2.9.2, etc.).
    Affected if The installed version is any version prior to 3.1.0 (such as 3.0.x, 2.x, or 1.x).
  3. Identify user input handlers in theme
    Examine theme PHP files for functions that process user-supplied data and interact with the WordPress database, such as $_GET, $_POST, $_REQUEST variables used in SQL queries. Common locations include template files with search forms, filter controls, or submission handlers.
    Affected if Theme files contain custom SQL queries that accept input from $_GET, $_POST, or $_REQUEST parameters without using $wpdb->prepare() or equivalent sanitization functions.
  4. Verify WordPress database user privileges
    Check the database user configured in wp-config.php (DB_USER) and review what database privileges are granted. Ensure the database user has only necessary privileges and not broad administrative access.
    Affected if The database user has broad privileges (such as DROP, DELETE, or FILE privileges) beyond SELECT, INSERT, UPDATE, which could be exploited for data exfiltration or privilege escalation.

The environment is affected if the HiStudy theme version is below 3.1.0 and the theme contains custom SQL query handlers that process unsanitized user input from web forms or URL parameters.
