Vulnerability Overview

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 Analysis

REMEDIATION: Update to version 1.3.28, or a newer patched version --- IDENTIFIER: CWE-862 (Missing Authorization) The product does not perform an authorization check when an actor attempts to access a resource or perform an action.
