CVE-2026-54649
NVD: punchin-email is a Cloudflare Email Worker that provides two-way role aliases while relaying mail to a private inbox. NVD: Prior to 1.5.0, handleInbound delivers inbound alias mail with message.forward(), which silently drops the added Reply-To header intended to route responses through the relay. NVD: When a correspondent sends mail to an alias and the operator replies, the mail client can send directly to the correspondent from the private FORWARD_TO inbox address, exposing that address.
