CVE-2026-82859: Kerberosmansour Hulumi

Critical severity, CVSS 9.8. EPSS: 0.5% chance of exploitation in the next 30 days.

hulumi versions before v1.3.2 contain a deployment SCP template that allows tag-on-create bypasses for hulumi:iac-role protections. Attackers can bypass intended IAM boundary restrictions by exploiting the weakened SCP template in downstream deployments.
