This is a fundamental access control design flaw, not merely a misconfiguration, meaning all deployed versions are affected with no vendor patch available. The lack of response from PayRange to CISA's mitigation requests compounds the risk, leaving organizations with no official remediation path. This matters because payment infrastructure APIs handle sensitive transactional and device data, making them high-value targets for fraud, disruption, and data theft.","**Immediate actions:**\n- Isolate PayRange API-connected devices behind a network firewall or VPN to restrict public-facing exposure until a patch is available.\n- Monitor all API traffic to and from PayRange endpoints for anomalous access patterns, unauthorized queries, or unexpected image modification events.\n\n**Long-term improvements:**\n- Require vendors to demonstrate authorization controls on all API endpoints as part of procurement and ongoing third-party security assessments.\n- Implement a formal vulnerability disclosure and vendor response SLA policy to escalate unresponsive vendors to leadership or replace them.\n- Enforce zero-trust principles by requiring explicit authentication and authorization checks on every API call, including management endpoints.\n\n**Detection measures:**\n- Deploy API gateway logging to capture all requests to management endpoints and alert on unauthenticated or anomalous access attempts.\n- Establish a process for tracking CISA Known Exploited Vulnerabilities (KEV) and ICS advisories relevant to operational technology and payment systems in your environment.",[12,13,14,15,16,17,18,19,20,21,22,23],"CIS Control 4: Secure Configuration of Enterprise Assets","CIS Control 6: Access Control Management","CIS Control 7: Continuous Vulnerability Management","NIST SP 800-53 AC-3: Access Enforcement","NIST SP 800-53 AC-17: Remote Access","NIST SP 800-53 IA-2: Identification and Authentication","NIST SP 800-53 RA-5: Vulnerability Monitoring and Scanning","NIST CSF PR.AC-4: Access Permissions and Authorizations","OWASP API Security Top 10: API1 - Broken Object Level Authorization","OWASP API Security Top 10: API5 - Broken Function Level Authorization","PCI DSS Requirement 6.3: Security Vulnerabilities are Identified and Addressed","PCI DSS Requirement 7: Restrict Access to System Components and Cardholder Data","published","2026-08-25T20:22:11.774462+00:00","2026-08-25T20:22:11.481+00:00",{"id":7,"url":28,"slug":29,"title":30},"https:\u002F\u002Fwww.cisa.gov\u002Fnews-events\u002Fics-advisories\u002Ficsa-26-237-04","payrange-api-131f46","PayRange API",[32,38,44],{"id":33,"name":34,"slug":35,"description":36,"color":37},"05757c8d-6b93-4194-b35d-7359e7d33b0e","Vulnerability Management","vulnerability-management","Missing scans, no risk prioritization","#fb923c",{"id":39,"name":40,"slug":41,"description":42,"color":43},"1ec88fde-2d0f-4ed8-932a-33f5ccc0fdc7","Access Control","access-control","Excessive privileges, missing MFA, weak auth","#f97316",{"id":45,"name":46,"slug":47,"description":48,"color":49},"af7fce9e-1ce8-4156-93bc-09dcfbfdf29d","Patch Management","patch-management","Unpatched vulnerabilities, delayed updates","#ef4444",[]]
