CyberRota Analysis

AI-Generated

The MetForm WordPress plugin prior to version 4.3.1 is vulnerable due to improper access restrictions on a debug file created in the web root during form submissions with HubSpot Forms integration enabled. This flaw allows unauthenticated attackers to access sensitive API response data, including correlation identifiers and cookies, potentially leading to data exposure or further exploitation. WordPress site administrators using the MetForm plugin should prioritize updating to version 4.3.1 or later to mitigate this risk.
