IBM i is Affected by an Improper Validation Vulnerability

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

IBM i 7.3, 7.4, 7.5, and 7.6 could allow a remote attacker to perform unauthorized manipulation of distributed transactions due to improper validation of attacker-supplied transaction identifiers.
