This is a critical design flaw: exposing a privileged communication channel with insufficient input validation effectively hands attackers a direct path to full system compromise. Compounding the risk, the official fix in Parallels Desktop 27 is incompatible with Intel-based Macs, meaning a significant portion of the user base has no vendor-supported remediation path. This situation highlights how end-of-support hardware\u002Fsoftware combinations can leave organizations permanently exposed, requiring compensating controls rather than straightforward patching.","**Immediate actions:**\n- Audit all Mac systems running Parallels Desktop and identify which are Intel-based to assess exposure scope.\n- Apply Parallels Desktop 27 immediately on all Apple Silicon Macs where the patch is compatible.\n- Restrict local user accounts on Intel Macs running Parallels to the minimum necessary privileges and monitor for suspicious root-level activity.\n\n**Compensating controls for unpatched systems:**\n- Consider uninstalling Parallels Desktop on Intel Macs where virtualization is non-essential until a fix or acceptable workaround is available.\n- Enforce endpoint detection and response (EDR) rules to alert on unexpected privilege escalations or prl_disp_service anomalies on Intel-based systems.\n- Apply strict file system permission audits to identify and lock down any other world-writable sockets or IPC endpoints on managed endpoints.\n\n**Long-term improvements:**\n- Establish a hardware and software lifecycle policy that flags products approaching end-of-support compatibility to avoid future unmitigable vulnerability scenarios.\n- Integrate CVE monitoring for all installed third-party applications into your vulnerability management program to ensure rapid detection of newly disclosed flaws.\n- Require vendors to provide compatibility matrices with patch releases during procurement and contract renewals.",[12,13,14,15,16,17,18,19,20,21],"CIS Control 2: Inventory and Control of Software Assets","CIS Control 4: Secure Configuration of Enterprise Assets and Software","CIS Control 7: Continuous Vulnerability Management","CIS Control 5: Account Management","NIST SP 800-53 AC-6: Least Privilege","NIST SP 800-53 SI-2: Flaw Remediation","NIST SP 800-53 CM-6: Configuration Settings","NIST SP 800-53 RA-5: Vulnerability Monitoring and Scanning","MITRE ATT&CK T1068: Exploitation for Privilege Escalation","ISO\u002FIEC 27001 A.12.6.1: Management of Technical Vulnerabilities","published","2026-09-16T16:21:44.154487+00:00","2026-09-16T16:21:43.828+00:00",{"id":7,"url":26,"slug":27,"title":28},"https:\u002F\u002Fthehackernews.com\u002F2026\u002F09\u002Fparallels-desktop-flaw-lets-non-admin.html","parallels-desktop-flaw-lets-non-admin-mac-users-gain-root-but-intel-macs-can-t-i-f1a5ac","Parallels Desktop Flaw Lets Non-Admin Mac Users Gain Root, but Intel Macs Can't Install Fix",[30,36,42],{"id":31,"name":32,"slug":33,"description":34,"color":35},"05757c8d-6b93-4194-b35d-7359e7d33b0e","Vulnerability Management","vulnerability-management","Missing scans, no risk prioritization","#fb923c",{"id":37,"name":38,"slug":39,"description":40,"color":41},"1ec88fde-2d0f-4ed8-932a-33f5ccc0fdc7","Access Control","access-control","Excessive privileges, missing MFA, weak auth","#f97316",{"id":43,"name":44,"slug":45,"description":46,"color":47},"af7fce9e-1ce8-4156-93bc-09dcfbfdf29d","Patch Management","patch-management","Unpatched vulnerabilities, delayed updates","#ef4444",[]]
