CWE

KEV

CWE ID	Description

Attack-Flow Graph

Executive Summary

This vulnerability is a parsing issue in how directory paths are handled. It allows a malicious app to bypass sandbox restrictions by exploiting improper path validation. The issue was fixed in specific versions of iOS, iPadOS, macOS, and tvOS.

Detection Guidance

This vulnerability is specific to Apple operating systems and relates to sandbox escape via directory path parsing. Detection requires checking system versions against patched releases: iOS 26.6, iPadOS 26.6, macOS Sequoia 15.7.8, macOS Sonoma 14.8.8, macOS Tahoe 26.6, or tvOS 26.6. No direct commands can detect exploitation attempts without additional context.

Impact Analysis

If exploited, this vulnerability could let a malicious app escape its sandbox. This means the app could access restricted system resources or data it should not be able to, potentially leading to unauthorized actions on your device.

Compliance Impact

The vulnerability allows a malicious app to break out of its sandbox, which could lead to unauthorized access to sensitive data. This may impact compliance with standards like GDPR (data protection) and HIPAA (health information privacy) by increasing the risk of data breaches.

Mitigation Strategies

Update affected Apple devices to the latest versions: iOS 26.6, iPadOS 26.6, macOS Sequoia 15.7.8, macOS Sonoma 14.8.8, macOS Tahoe 26.6, or tvOS 26.6 to address the sandbox escape vulnerability.
