Overview

Affected versions of this package are vulnerable to Exposure of Sensitive System Information to an Unauthorized Control Sphere via the REST API error handler returning unsanitized PHP error messages that include the full filesystem path. An attacker can obtain sensitive system path information by triggering errors through unauthenticated API requests. This is only exploitable if the REST API is enabled and not disabled with the 'api' => false option.
