CVE-2026-18154 is a high-severity use of hard-coded cryptographic key vulnerability in Financial Transaction Manager (FTM) for RedHat OpenShift from IBM, with a CVSS 3.1 base score of 7.5 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. Affected Financial Transaction Manager (FTM) for RedHat OpenShift versions: 4.0.6.0. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.26% chance of exploitation within 30 days, which is low compared with other CVEs.

Next patch cycle

High severity with no evidence of exploitation so far.

What to do

  1. Update Financial Transaction Manager to 4.0.11.0 or a later version.
  2. Read the advisory on ibm.com for workarounds and exact fixed builds.
  3. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
