CVE-2026-80344Network attack vectorHinoki check available

SSRF via unchecked asynchronous receipt destination

Published Oct 19, 2026 · Updated Oct 19, 2026

SSRF in Apache Camel's AS2 component allows remote attackers to reach internal hosts through asynchronous receipt delivery. AS2AsynchronousMDNManager.send() uses the inbound Receipt-Delivery-Option header to open an outbound socket without restricting the destination to deployment-approved hosts. Exploitation requires an AS2 receiver accepting the sender's message; configured MDN delivery credentials also leak when the destination is attacker-controlled.
