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
The Career Section plugin for WordPress is vulnerable to Arbitrary File Upload in all versions up to, and including, 1.7 via the CV upload handler. This is due to missing file type validation. This makes it possible for unauthenticated attackers to upload files that may be executable, which makes remote code execution possible.

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 · high confidence

The Career Section plugin for WordPress lacks proper file type validation in its CV upload handler, allowing unauthenticated attackers to upload arbitrary executable files. This enables remote code execution since uploaded files can be stored in a web-accessible location and subsequently invoked.

MitigationUpdate the Career Section plugin to version 1.8 or later which includes file type validation. If immediate update is not possible, disable the CV upload functionality or implement web server-level restrictions to prevent execution of uploaded files.

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 Career Section plugin is installed
    In WordPress admin, go to Plugins > Installed Plugins and look for 'Career Section' or a plugin that handles job applications/CV uploads. Alternatively, check the wp-content/plugins directory for career-section or similar folder names.
    Affected if The Career Section plugin (or similar CV upload plugin) is present in the WordPress installation
  2. Check the installed plugin version
    In WordPress admin under Plugins, find the Career Section plugin and view its version number. Compare this to version 1.8.
    Affected if The installed version is earlier than 1.8, or the version cannot be determined (plugin may be unmaintained)
  3. Confirm CV upload functionality is exposed
    Visit the public careers/jobs page on the website that uses the plugin. Look for a CV/resume upload form. Check if the endpoint accepts file uploads without authentication.
    Affected if A CV upload form exists and accepts files without requiring login or authentication
  4. Verify uploaded files are web-accessible
    If possible, upload a harmless test file (e.g., a text file) via the CV form and check the response for a URL or path where the file is stored. Determine if that location is within the web root (publicly accessible).
    Affected if Uploaded files are stored in a directory accessible via HTTP/HTTPS (within the web root)
  5. Check for file type restrictions on upload
    Inspect the HTML form or test by attempting to upload a file with a non-standard extension (e.g., .php, .exe, .phtml). Observe whether the upload is rejected based on file extension or MIME type.
    Affected if The upload accepts executable file types (.php, .exe, .phtml, .js) without validation, or no file type restriction is visible

You are affected if the Career Section plugin is installed with a version earlier than 1.8, the CV upload form is publicly accessible, and uploaded files can be executed from a web-accessible location.
