IBM Financial Transaction Manager for RedHat OpenShift: remote code execution

High8.8CVE-2026-18490 · Published Sep 23, 2026

IBM Financial Transaction Manager (FTM) for RedHat OpenShift is vulnerable to unauthenticated remote code execution via Java native deserialization on the PayDir Business Rules Manager RMI SSL endpoint (BrmRMISSLServerSocketFactory.java:95, EP8). An adjacent-network attacker can deliver a crafted serialized payload to achieve arbitrary code execution, exposing all PayDir credentials and enabling manipulation of payment business rules.
