IBM Financial Transaction Manager (FTM) for RedHat OpenShift could allow a remote attacker to cause a denial of service due to allocation of resources without limits or throttling.
AnalysisAI
Resource exhaustion in IBM Financial Transaction Manager (FTM) for Red Hat OpenShift allows unauthenticated attackers on an adjacent network segment to force a denial-of-service condition by driving endpoint behavior that allocates resources without limits or throttling (CWE-770). The assigned CVSS 3.1 vector (AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H, base 6.5) confines the attack surface to callers who can already reach a vulnerable FTM endpoint from the same network segment or cluster network, and limits the outcome to availability loss - service crash or hang - with no confidentiality or integrity impact. …

Vulnerability AssessmentAI
| Exploitation | Requires network adjacency to the IBM FTM for RedHat OpenShift instance (AV:A) - the attacker must reach a vulnerable FTM endpoint from the same network segment/cluster network, not across the public internet. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a mid-severity availability issue, not an urgent priority. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Patch available per vendor advisory: IBM has published remediation guidance for CVE-2026-18170 at https://www.ibm.com/support/pages/node/7288641, and the available data confirms a vendor patch exists, though it does not name an exact fix version - consult that advisory for the precise FTM for Red Hat OpenShift release level to install and follow IBM's documented upgrade procedure. … Detailed patch versions, workarounds, and compensating controls in full report. |
