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 Bravis-Themes Bravis Addons bravis-addons allows Using Malicious Files.This issue affects Bravis Addons: from n/a through <= 1.3.0.

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

Bravis Addons WordPress plugin up to version 1.3.0 contains an unrestricted file upload vulnerability allowing attackers to upload dangerous file types (e.g., PHP shells, executables) without proper validation. This can lead to remote code execution if uploaded files are accessible and executable within the web root.

MitigationImplement strict allowlist-based file type validation with magic byte verification, rename uploaded files to random names, store uploads outside the web root or disable script execution, and add proper nonce and capability checks to the upload handler.

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 Bravis Addons plugin is installed
    Check the WordPress plugins directory (wp-content/plugins/) for a folder named 'bravis-addons' or 'bravis' or inspect the installed plugins list via WordPress admin at Plugins > Installed Plugins
    Affected if The Bravis Addons plugin folder exists in the WordPress plugins directory
  2. Determine the installed plugin version
    Open the main plugin PHP file (typically bravis-addons.php) and locate the 'Version' header in the plugin comment block, or view the version in the WordPress admin plugins page
    Affected if The installed version is 1.3.0 or any version lower than 1.3.0
  3. Identify if the plugin exposes a file upload function
    Search the plugin directory for upload-related code: look for 'wp_handle_upload', 'move_uploaded_file', 'multipart/form-data', or 'file_upload' in PHP files within the plugin folder
    Affected if The plugin contains file upload handling code that accepts user-submitted files
  4. Check the upload directory is web-accessible with script execution enabled
    Inspect the upload path configuration - default WordPress uploads are in wp-content/uploads/ and are typically web-accessible; verify if .htaccess or similar restrictions prevent PHP execution in this directory
    Affected if Uploaded files can be stored in a directory accessible via web browser and PHP execution is not disabled in that directory

You are affected if the Bravis Addons plugin version 1.3.0 or lower is installed, contains active file upload functionality, and allows files to be stored in a web-accessible directory where scripts can execute.
