CVE-2026-20626 is a high-severity vulnerability affecting Apple's iOS, iPadOS, macOS, and visionOS. Rated with a CVSS score of 7.8, this vulnerability allows a malicious app to potentially gain root privileges on affected devices. The implications of this vulnerability are significant, as it could enable unauthorized access to sensitive data and system controls.
Organizations using these Apple operating systems should prioritize patching to the latest versions, specifically iOS 26.3, iPadOS 26.3, macOS Sequoia 15.7.4, macOS Tahoe 26.3, and visionOS 26.3. The exploitability of this vulnerability is considered high, with the potential for widespread impact.
Given the nature of this vulnerability and its potential for exploitation, organizations must take immediate action to secure their systems. This entails not only applying patches but also reviewing security policies and practices to mitigate future risks.
Risk to organizations includes unauthorized access to critical systems and data breaches, making it imperative for affected users to ensure their devices are updated without delay. Organizations should address this vulnerability in their priority patch cycle.
Vulnerability Details
This vulnerability allows a malicious app to gain root privileges, which can lead to severe security implications. It has been classified under CWE-862, indicating a potential elevation of privilege issue. The official description states that the vulnerability has been addressed with improved checks in the latest versions of the affected operating systems.
The CVSS score of 7.8 categorizes this vulnerability as high. The attack vector is local, and the attack complexity is low, requiring minimal privileges for exploitation. There is no user interaction required, which enhances the risk level.
The affected products include iOS, iPadOS, macOS (both Sequoia and Tahoe), and visionOS. The vulnerability was published on February 11, 2026, and has since been modified, indicating ongoing attention from Apple regarding its security posture.
Technical Analysis
The root cause of CVE-2026-20626 stems from insufficient checks within the system that allow for the escalation of privileges by malicious applications. The local attack vector indicates that an attacker must have physical or local access to the device, which could be facilitated through malicious applications installed on the device.
With low attack complexity and low privileges required for exploitation, this vulnerability poses a significant risk to users who may unwittingly install compromised applications. The impacts on confidentiality, integrity, and availability are high, as attackers could gain complete control over the device.
To mitigate these risks, Apple has introduced fixed versions in the latest updates. Users must ensure they upgrade to the patched versions promptly to avoid potential exploitation.
Risk & Impact Analysis
The real-world deployment risk associated with CVE-2026-20626 is substantial. Organizations relying on Apple operating systems should recognize the critical nature of this vulnerability, especially in environments where sensitive information is processed or stored. The potential blast radius includes any devices running the affected operating systems, leading to a wide-reaching risk of data breaches.
Organizations should assess their current exposure by identifying devices running outdated software and prioritizing updates to the latest versions. The urgency of this vulnerability, combined with its high CVSS score, necessitates immediate action within the organization's patch management cycle.
