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 checksWork through these to decide whether this CVE applies to you.
-
Locate Kapee theme versionAccess the WordPress site files via FTP or file manager, navigate to wp-content/themes/kapee/, and open style.css to find the 'Version:' headerAffected if Version is below 1.7.1 (e.g., 1.7.0, 1.6.9, etc.)
-
Check if theme is activeLog into WordPress admin dashboard, go to Appearance > Themes, and verify if Kapee is the currently active themeAffected if Kapee theme is active and version is below 1.7.1
-
Search for unsanitized input in theme filesUse a code search tool to scan PHP files in the kapee theme directory for patterns like 'echo $_GET', 'echo $_REQUEST', or 'print $_POST' without corresponding sanitization functions such as esc_html or esc_urlAffected if Unsanitized user-supplied input is found in output statements and version is below 1.7.1
-
Inspect AJAX handlers for XSS pointsReview PHP files containing wp_ajax or wp_ajax_nopriv hooks, looking for parameters that are echoed back to the user without proper escapingAffected if AJAX handlers accept and output user input without sanitization and theme version is below 1.7.1
The environment is affected if the Kapee WordPress theme version is below 1.7.1 and the theme is installed and active on the WordPress site

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedUpgrade Kapee theme to version 1.7.1 or later to remediate the vulnerability.
Kapee 1.7.1
- 1. Identify the Kapee theme or plugin installed on your WordPress site
- 2. Check the current installed version of Kapee in your WordPress admin dashboard (typically under Appearance > Themes or Plugins > Installed Plugins)
- 3. If the installed version is below 1.7.1, initiate an upgrade to version 1.7.1 or later
- 4. Before upgrading, backup your WordPress site including database and files
- 5. Test the upgrade in a staging environment first if possible
- 6. Apply the upgrade through WordPress admin or via FTP/SFTP if admin access is unavailable
- 7. Verify the upgrade was successful and confirm the new version number
- 8. Test critical site functionality to ensure the update did not break existing features
