CVE-2026-86966 · Severity: info · Published 2026-10-26

Apple's operating systems (iOS, iPadOS, macOS, and visionOS) handle file system access through a core service that manages which files applications can read or modify. An attacker can exploit a flaw in how symbolic links are processed to bypass these protections and modify sensitive system files. This could allow a malicious app to gain elevated privileges or compromise system integrity.

## Technical details

A symlink following vulnerability in Apple's file system access control allows an app to modify protected portions of the file system. The flaw is mitigated through improved symlink handling and path validation in APFS and related components. An attacker with app execution privileges can craft malicious symbolic links to bypass file access restrictions and write to protected locations.
