Lifecycle Timeline
5DescriptionCVE.org
A path traversal issue was addressed with improved input validation. This issue is fixed in macOS Sequoia 15.7.8, macOS Sonoma 14.8.8, macOS Tahoe 26.6. An app may be able to break out of its sandbox.
AnalysisAI
Sandbox escape via path traversal in macOS allows a malicious app to read and write files outside its sandbox, potentially accessing sensitive data. Affects macOS versions prior to Sequoia 15.7.8, Sonoma 14.8.8, and Tahoe 26.6, with no privileges needed but requiring user interaction to launch the crafted app. No active exploitation or public exploit code known at time of analysis; EPSS indicates low exploitation probability.
Technical ContextAI
The vulnerability lies in macOS's input validation mechanism used during file path resolution, failing to properly filter directory traversal sequences (e.g., '../') per CWE-22. The affected product, identified by CPE cpe:2.3:a:apple:macos:*:*:*:*:*:*:*:*, spans all macOS versions prior to the patched releases. When exploited, the flaw allows an application to bypass sandbox restrictions, violating the containment model designed to isolate app data. The root cause is inadequate sanitization of user‑supplied file paths by an operating‑system component, which can be triggered by any ordinary app without requiring elevated permissions.
RemediationAI
Apply the vendor‑supplied update by upgrading to macOS Sequoia 15.7.8, macOS Sonoma 14.8.8, or macOS Tahoe 26.6. Official patches are referenced in Apple's security advisories (support.apple.com/en-us/128067, 128071, 128072). No workarounds are documented; the primary mitigation is to install the fix. In the interim, risk can be lowered by practicing caution with untrusted applications, but this does not eliminate the underlying flaw.
