Overview
Affected versions of this package are vulnerable to Improper Input Validation due to improper validation of HTTP headers in the headerFilterStrategy process. An attacker can manipulate HTTP headers to inject unauthorized directives or bypass intended header filtering by sending specially crafted requests to endpoints using the default configuration. This may allow the attacker to influence routing or deliver messages to unintended recipients.
