Overview
Affected versions of this package are vulnerable to Uncaught Exception via the ValidationHandler process. An attacker can cause the application to panic and disrupt service availability by sending HTTP requests with non-canonical or unsupported HTTP method tokens to any existing static path, resulting in aborted connections and unbounded error log growth before authentication is performed. This is only exploitable if the targeted path is a static (non-templated) endpoint defined in the OpenAPI specification.
