CVE-2026-43723

Apple · iOS, iPadOS, macOS, tvOS, visionOS, watchOS

A path handling vulnerability in multiple Apple operating systems allows local applications to potentially escalate privileges to root.

Executive summary

A critical path validation flaw across the Apple ecosystem may allow local applications to gain unauthorized root privileges.

Vulnerability

This is a privilege escalation vulnerability stemming from improper path validation. A local attacker, requiring low privileges, can exploit this flaw to execute code with root-level permissions.

Business impact

The ability for a standard user or malicious application to gain root access represents a total compromise of the affected device. This could lead to complete data exfiltration, installation of persistent malware, and total loss of system integrity. With a CVSS score of 7.8, this vulnerability is categorized as high severity due to the potential for full system takeover.

Remediation

Immediate Action: Update all affected Apple devices to the latest available software version as specified in the official Apple security support documentation.

Proactive Monitoring: Review system logs for unauthorized attempts to access restricted directories or unusual binary execution patterns associated with privilege escalation.

Compensating Controls: Implement mobile device management (MDM) policies to restrict the installation of unauthorized or unverified applications.

Exploitation status

Public Exploit Available: False

Analyst recommendation

Given the high impact of this privilege escalation vulnerability, security teams must prioritize the deployment of Apple security updates across their device fleets. Ensuring that all endpoints are running the latest versions is the most effective way to eliminate the risk of unauthorized root access.
