CVE-2026-48036 High · 8.4 CWE-755 Jul 24, 2026

Hulumi: Drift classifier fails open on adapter errors and over-promotes Mixed verdicts

Hulumi is an open-source toolkit that ships secure-by-default cloud and platform infrastructure components for Pulumi. Prior to version 1.4.0, consumers running drift detection in CI / cron could see transient adapter failures silently cached as "all clear" — masking real attacks for up to six hours — or see ordinary provider-version churn falsely promoted to incident severity. Either way, the verdict source was unreliable for downstream incident workflows that gate on it. This issue has been patched in version 1.4.0.

CVE-2026-48035 High · 7.1 CWE-1059 Jul 24, 2026

Hulumi: AccountFoundation audit-delivery S3 bucket could be silently weakened

Sandbox-tier deployments had no audit immutability at all (defects 1 and 3 compounded). This issue has been patched in version 1.4.0.
