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.

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

Unrestricted file upload vulnerability in the Corpkit WordPress theme allows attackers to upload dangerous file types (web shells) directly to the web server without proper validation, potentially achieving full remote code execution and server compromise.

MitigationImmediately disable or remove the Corpkit theme/plugin until a security patch is available; implement strict allowlist-based file type validation, store uploads outside webroot, and disable script execution in upload directories.

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 Corpkit theme is installed
    Navigate to Appearance > Themes in WordPress admin dashboard, or check /wp-content/themes/ directory for corpkit theme folder
    Affected if Corpkit theme folder exists in /wp-content/themes/
  2. Determine Corpkit theme version
    Check theme style.css header or version.php file within the corpkit theme folder for version number
    Affected if Version is unknown or falls within unpatched range (no patched version specified in CVE data)
  3. Identify file upload functionality
    Search theme files for upload handlers: look for code handling file uploads in functions.php, or any plugin-like features that accept file uploads
    Affected if Theme contains file upload code that accepts user-submitted files
  4. Check for file type validation
    Review upload handling code for allowlist/denylist validation of file extensions, MIME type checks, and content-type verification
    Affected if No file type validation exists, or validation can be easily bypassed (accepts .php, .phtml, .exe etc.)
  5. Verify upload directory configuration
    Check if uploaded files are stored within webroot and if .htaccess or similar prevents script execution in upload directories
    Affected if Uploads are stored in web-accessible directories without disabling script execution

User is affected if Corpkit theme is installed and contains unrestricted file upload functionality without proper validation controls.
