Lifecycle Timeline
5DescriptionCVE.org
@hulumi/policies versions before 1.3.2 contain a parent spoof bypass vulnerability that allows attackers to submit spoofed SecureBucket parent evidence during policy evaluation. Attackers can bypass security policy checks by providing falsified evidence, causing the validator to miss unsafe bucket configurations.
AnalysisAI
Policy evaluation bypass in @hulumi/policies before 1.3.2 permits unauthenticated remote attackers to submit forged SecureBucket parent evidence, causing the validator to incorrectly classify unsafe bucket configurations as compliant and bypass associated security controls. The flaw (internally tracked as HULUMI-H1) exists because the validator did not correlate submitted evidence against the expected component-to-resource relationship, allowing fabricated evidence to satisfy policy checks. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires the ability to submit arbitrary policy evaluation input to an application that uses @hulumi/policies for SecureBucket (HULUMI-H1) policy checks - specifically, the attacker must be able to control the evidence object passed to the validator. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The provided CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N) yields a base score of 8.7, reflecting network-reachable, low-complexity, unauthenticated exploitation with high confidentiality impact on the vulnerable system. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Vendor-released patch: 1.3.2. … Detailed patch versions, workarounds, and compensating controls in full report. |
