This means unauthenticated or low-privileged users can perform actions reserved for administrators, directly threatening the financial integrity of online stores. Active exploitation in the wild means that unpatched sites are already being targeted, not just theoretically at risk. The root failure is twofold: the module shipped without adequate authorization enforcement, and site operators failed to apply the patch before attackers weaponized the vulnerability.","**Immediate actions:**\n- Apply Drupal's official patch or upgrade Commerce Core to the latest patched release immediately on all affected instances.\n- Conduct an emergency audit of Commerce Core access logs to identify any suspicious transactions or unauthorized administrative actions that may indicate prior exploitation.\n\n**Long-term improvements:**\n- Implement automated vulnerability scanning for all internet-facing CMS and e-commerce components, with alerts triggered when critical CVEs are published.\n- Enforce a formal patch management policy requiring critical vulnerabilities to be remediated within 24–72 hours of vendor disclosure.\n- Maintain a complete, up-to-date software inventory (SBOM) for all web applications to quickly identify affected components when new CVEs emerge.\n\n**Detection measures:**\n- Deploy a Web Application Firewall (WAF) with rules targeting authorization bypass patterns to detect and block exploitation attempts in real time.\n- Enable centralised logging of all authorization decisions and administrative actions within the Drupal application, and alert on anomalous privilege escalations.",[12,13,14,15,16,17,18],"CIS Control 7: Continuous Vulnerability Management","NIST SP 800-53 SI-2: Flaw Remediation","NIST CSF 2.0 PR.AA: Identity Management, Authentication, and Access Control","ISO\u002FIEC 27001:2022 A.8.8: Management of technical vulnerabilities","OWASP A06:2021 Vulnerable and Outdated Components","PCI DSS Requirement 6","NIS2 Article 21(2)(b)",{"NIS2 Article 21(2)(b)":20,"PCI DSS Requirement 6":21,"NIST SP 800-53 SI-2: Flaw Remediation":22,"OWASP A06:2021 Vulnerable and Outdated Components":23,"CIS Control 7: Continuous Vulnerability Management":24,"ISO\u002FIEC 27001:2022 A.8.8: Management of technical vulnerabilities":25,"NIST CSF 2.0 PR.AA: Identity Management, Authentication, and Access Control":26},"NIS2 requires essential and important entities to implement vulnerability handling and patching policies;
