Evidence Validation Bypass in Policy Validators

The @hulumi/policies vulnerability (CVE-2026-82855) is a critical evidence validation bypass affecting Cloudflare and deployment-governance validators before version 1.3.2. This flaw allows attackers to suppress legitimate security violations by submitting compliant evidence from unrelated resources—such as different zones, hostnames, origins, or repositories—to satisfy policy requirements for resources they cannot actually secure. Organizations using this library for infrastructure-as-code governance, multi-tenant deployments, or cross-zone security validation are at immediate risk, as attackers can effectively disable security guardrails that are meant to enforce compliance across their entire stack.

While this CVE doesn't map directly to MITRE ATT&CK techniques, Casky's AI-driven security skills approach would detect the attack patterns through behavioral analysis of policy validation chains and evidence submission workflows. Practitioners would observe anomalous findings such as: evidence sourced from mismatched resource identifiers, policy exemptions granted without corresponding remediation in the target resource, or validation records showing compliant status for resources that failed independent security checks. Casky's extended reasoning capabilities would flag the logical inconsistency between submitted evidence and the resource under evaluation—a pattern consistent with Defense Evasion and Privilege Escalation tactics—enabling teams to identify and revoke malicious policy bypasses before they compromise production environments.
