CVE-2026-48036
Hulumi: Drift classifier fails open on adapter errors and over-promotes Mixed verdicts
Description
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.

Action Type Old Value New Value Added Translation Title: hulumi de kerberosmansour, Description: Hulumi es un conjunto de herramientas de código abierto que distribuye componentes de infraestructura de nube y plataforma seguros por defecto para Pulumi. Antes de la versión 1.4.0, los usuarios que ejecutaban detección de desvíos en CI / cron podían ver fallos transitorios del adaptador almacenados en caché silenciosamente como ’todo despejado’ - enmascarando ataques reales durante hasta seis horas - o ver la rotación ordinaria de versiones del proveedor falsamente elevada a gravedad de incidente. De cualquier manera, la fuente del veredicto no era fiable para los flujos de trabajo de incidentes posteriores que la utilizan como criterio. Este problema ha sido parcheado en la versión 1.4.0. -
