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
Unrestricted Upload of File with Dangerous Type vulnerability in appointify Appointify appointify allows Upload a Web Shell to a Web Server.This issue affects Appointify: from n/a through <= 1.0.8.

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

The Appointify application through version 1.0.8 lacks proper validation on uploaded files, allowing authenticated users to upload dangerous file types (such as PHP web shells) that can be executed on the server for remote code execution.

MitigationImplement strict allowlist-based file type validation, store uploads outside the webroot, rename uploaded files, and disable script execution in the upload directory.

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. Identify Appointify installation and version
    Locate the Appointify application files and check the version number in the application metadata, configuration, or about page. Compare against the affected version range (1.0.8 and below).
    Affected if The installed version of Appointify is 1.0.8 or lower.
  2. Verify if file upload functionality exists
    Identify whether the Appointify application includes a file upload feature (typically in admin panels, user profiles, or appointment attachment sections).
    Affected if The application has an active file upload feature accessible to authenticated users.
  3. Check file type validation configuration
    Inspect the upload handler code or application configuration for any file type or extension validation logic. Look for allowlists or blocklists governing permitted upload types.
    Affected if There is no file type validation, weak validation (e.g., client-side only), or the validation allows executable extensions like .php, .php5, .phtml, .exe, or .js.
  4. Determine upload directory web accessibility
    Locate the directory where uploaded files are stored. Verify if this directory is web-accessible (within the webroot) and whether script execution is enabled or disabled in that location.
    Affected if Uploaded files are stored within the webroot and script execution is not disabled (e.g., no .htaccess restrictions or equivalent).

You are affected if the Appointify version is 1.0.8 or lower and the application has a web-accessible upload feature without proper file type validation.
