CVE-2025-46289

5.5 MEDIUM

📋 TL;DR

A logic flaw in macOS file handling allows applications to bypass intended access restrictions and read protected user data. This affects macOS systems running vulnerable versions before the patched releases. Users with sensitive data stored in protected locations are at risk.

💻 Affected Systems

Products:
  • macOS
Versions: Versions prior to macOS Tahoe 26.2, macOS Sequoia 15.7.3, macOS Sonoma 14.8.3
Operating Systems: macOS
Default Config Vulnerable: ⚠️ Yes
Notes: All default macOS installations running affected versions are vulnerable. The vulnerability is in the operating system's file handling logic.

⚠️ Risk & Real-World Impact

🔴

Worst Case

Malicious applications could access sensitive user data including documents, credentials, or personal information stored in protected locations, leading to data theft or privacy violations.

🟠

Likely Case

Malware or compromised legitimate applications could access user data they shouldn't have permission to read, potentially exposing personal or sensitive information.

🟢

If Mitigated

With proper application sandboxing and security controls, exploitation would be limited to specific contexts, though data exposure risk remains.

🌐 Internet-Facing: LOW - This vulnerability requires local application execution, not remote network access.
🏢 Internal Only: MEDIUM - Malicious or compromised applications on the local system could exploit this to access protected data.

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ✅ No
Complexity: MEDIUM

Exploitation requires a malicious or compromised application to be installed and executed on the target system. No public exploit code is currently known.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: macOS Tahoe 26.2, macOS Sequoia 15.7.3, macOS Sonoma 14.8.3

Vendor Advisory: https://support.apple.com/en-us/125886

Restart Required: Yes

Instructions:

1. Open System Settings > General > Software Update. 2. Install available macOS updates. 3. Restart the system when prompted.

🔧 Temporary Workarounds

Application Sandboxing Enforcement

macOS

Use macOS privacy controls to restrict application access to sensitive data locations

Open System Settings > Privacy & Security > Files and Folders to review and restrict application permissions

🧯 If You Can't Patch

  • Restrict installation of untrusted applications using macOS Gatekeeper and only install from App Store or identified developers
  • Use separate user accounts for sensitive work and limit application permissions through System Settings > Privacy & Security

🔍 How to Verify

Check if Vulnerable:

Check macOS version in System Settings > General > About. If version is earlier than Tahoe 26.2, Sequoia 15.7.3, or Sonoma 14.8.3, the system is vulnerable.

Check Version:

sw_vers

Verify Fix Applied:

Verify macOS version is at least Tahoe 26.2, Sequoia 15.7.3, or Sonoma 14.8.3 in System Settings > General > About.

📡 Detection & Monitoring

Log Indicators:

  • Unusual file access patterns by applications, particularly to protected directories
  • Console.app logs showing unexpected file permission errors or access attempts

Network Indicators:

  • No direct network indicators as this is a local vulnerability

SIEM Query:

macOS endpoint logs showing file access violations or unexpected application behavior with file system operations
