Impact

Without a published CVSS vector, EPSS score, or KEV status from CISA, the real-world risk assessment relies on the nature of the vulnerability itself. The vulnerability is classified as an information disclosure issue with a permissions/authorization root cause, suggesting local attack vector (an application must run on the system) with likely low-to-medium complexity depending on how easily an attacker can craft a malicious app. The fact that Apple released patches across three major OS versions indicates this was a cross-version issue deemed important enough for coordinated remediation. The absence of CVSS scoring and public POC suggests this may not be actively exploited in the wild, but the broad patch distribution across multiple OS generations indicates significant scope. Priority should be elevated given the sensitivity of protected user data (contacts, photos, location, health) and the ease with which a local application could exploit this if delivered via malware or a compromised app.

Exploit ScenarioDerived

An attacker distributes a malicious application (via phishing, app store compromise, or supply chain attack) that, once installed and executed on a vulnerable macOS system, exploits the permissions enforcement weakness to access protected user data such as photos, contacts, location history, or health information without displaying the normal permission prompts or requiring explicit user consent. The attacker exfiltrates this sensitive data to a remote server, compromising user privacy at scale. Since the attack requires local execution of an application, it would typically be delivered as part of a broader malware campaign or social engineering attack targeting macOS users.

AnalysisAIv1 – Mar 25, 2026

A permissions enforcement vulnerability in macOS allows applications to bypass security restrictions and access protected user data due to insufficient authorization checks. This issue affects macOS Sequoia (prior to 15.7.5), macOS Sonoma (prior to 14.8.5), and macOS Tahoe (prior to 26.4). An attacker with the ability to execute an application on the affected system could potentially access sensitive user information without proper user consent or authorization. No CVSS score, EPSS data, or active exploitation in the wild (KEV status) has been disclosed by Apple.

RemediationAI

Immediately apply the latest security updates provided by Apple: upgrade macOS Sequoia to version 15.7.5 or later, upgrade macOS Sonoma to version 14.8.5 or later, or upgrade macOS Tahoe to version 26.4 or later. Users should check System Preferences > General > Software Update to download and install the latest patches, which require a system restart. For organizations, deploy these updates through Mobile Device Management (MDM) or macOS security update tools to ensure rapid deployment across all systems. As a temporary mitigation prior to patching, restrict user permissions to install untrusted applications, disable third-party app installation, and enable Gatekeeper and XProtect settings to prevent execution of potentially malicious applications. Refer to the vendor advisories at https://support.apple.com/en-us/126794, https://support.apple.com/en-us/126795, and https://support.apple.com/en-us/126796 for additional details and deployment guidance.

Technical ContextAI · show details

This vulnerability stems from a permissions and access control issue within the macOS operating system, classified as an information disclosure weakness. The root cause involves insufficient enforcement of user data protection mechanisms, allowing applications to circumvent the permission boundaries that normally restrict access to sensitive user files and information. The affected product is the Apple macOS operating system across multiple major versions (Sequoia 15.x, Sonoma 14.x, and Tahoe 26.x), as indicated by CPE identifiers matching 'cpe:2.3:a:apple:macos'. Rather than a specific vulnerable library or protocol, this represents a system-level authorization control defect where the OS kernel or system frameworks fail to properly validate application entitlements before granting access to protected data categories such as contacts, photos, location, health data, or other privacy-sensitive information.

DescriptionCVE.org

A permissions issue was addressed with additional restrictions. This issue is fixed in macOS Sequoia 15.7.5, macOS Sonoma 14.8.5, macOS Tahoe 26.4. An app may be able to access protected user data.

Executive ViewAI

Why It Matters

Organizations using A permissions should be aware of moderate risk from CVE-2026-20607, a improper privilege management vulnerability rated CVSS 4.0. Attackers could gain access beyond their authorized level. Organizations should apply vendor updates when available and monitor for exploitation.

Business Impact: Low
Compensating Controls

Apply vendor patch. If patching is delayed: restrict network access and enable monitoring.
