CVE-2026-18505
MediumCVSS 5.4Summary
IBM Financial Transaction Manager (FTM) for RedHat OpenShift is vulnerable to open redirect in the PMP HostHeaderFilter (HostHeaderFilter.java:151). An unauthenticated attacker can craft a request with a manipulated Host header to redirect authenticated operators to attacker-controlled sites, enabling credential phishing.
Risk Assessment
The risk includes credential phishing of operators, which could lead to account takeover and system security compromise.
Recommendation
Update FTM to a patched version and configure Host header validation to reject unexpected values.
