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 GSheetConnector For Gravity Forms plugin for WordPress is vulnerable to authorization bypass in versions less than, or equal to, 1.3.27. This is due to a missing capability check on the 'install_plugin' function. This makes it possible for authenticated attackers, with subscriber-level access and above to install plugins on the target site and potentially achieve arbitrary code execution on the server under certain conditions.

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 GSheetConnector For Gravity Forms WordPress plugin versions 1.3.27 and below lack a capability check on the 'install_plugin' function, allowing any authenticated user with subscriber-level permissions or higher to trigger plugin installations. This broken access control vulnerability enables attackers to install malicious or vulnerable plugins and achieve arbitrary code execution on the WordPress server.

MitigationUpdate the plugin to version 1.3.28 or later which includes the missing capability check. If no patched version is available, remove the plugin immediately and review user role assignments to ensure no unauthorized users have elevated access.

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. Check installed plugin version
    Navigate to WordPress admin > Plugins > GSheetConnector For Gravity Forms and note the version number displayed, or check the plugin's main PHP file for the 'Version' header in the plugin comment block
    Affected if The version is 1.3.27 or lower
  2. Verify WordPress user accounts
    Go to Users > All Users in WordPress admin and review the list of registered users. Note any users assigned the Subscriber role or any role with authenticated access
    Affected if There are any user accounts with subscriber-level permissions or higher that should not have site access
  3. Check for unexpected plugin installation capabilities
    Review the plugin files (typically in wp-content/plugins/gsheetconnector-gravity-forms/) for AJAX handlers or functions that call plugins_api() or perform plugin installation without current_user_can('install_plugins') verification
    Affected if The plugin code allows plugin installation without proper capability verification or uses a flawed capability check

Your environment is affected if the GSheetConnector For Gravity Forms plugin version is 1.3.27 or below AND any authenticated user with subscriber-level or higher access exists on the site.
