CVE-2026-48037Network attack vector

Monitoring downgrade via unchecked detective-service reuse

Published Jul 24, 2026 · Updated Jul 24, 2026

Protection mechanism failure in Hulumi @hulumi/baseline before 1.4.0 allows remote authenticated users to weaken AWS monitoring. AccountFoundation imports reused GuardDuty detectors without validating their state or cadence and creates Security Hub subscriptions without retention on deletion. Reuse mode is required; affected deployments can report a false-positive baseline or disable existing CIS and NIST monitoring during stack teardown.
