IdentifiersCVE-2026-39871CWE-22

CVE-2026-39871 is a path handling flaw in Apple TV App affecting macOS Sonoma, macOS Sequoia, and macOS Tahoe. Apple describes the issue as a path handling issue that was addressed with improved logic. Successful exploitation could allow an application to observe unprotected user data, indicating improper handling or validation of file paths or path-derived resource access within the TV App.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

A local application may be able to observe user data that should not have been exposed to it. The disclosed data is described by Apple as unprotected user data; based on the available information, this is an information disclosure/privacy issue rather than code execution or privilege escalation.

Mitigation

If you can’t patch tonight, do this now.

If immediate patching is not possible, reduce exposure by limiting execution of untrusted or unnecessary local applications, enforcing application allowlisting where feasible, and restricting access to sensitive user data through standard macOS hardening and least-privilege controls. No vendor-specific workaround beyond installing the fixed releases is provided in the available content.

Remediation

Patch, then assume compromise.

Apply the vendor fixes provided by Apple. Apple states the issue is fixed in macOS Sequoia 15.7.7, macOS Sonoma 14.8.7, and macOS Tahoe 26.5. Upgrading to one of these versions or later remediates the vulnerability.
