⚠️ Risk & Real-World Impact

🔴

Worst Case

Malicious application could access sensitive user data including personal files, credentials, or private information without user consent.

🟠

Likely Case

Malicious applications could access limited sensitive data from sandboxed areas or user-accessible directories.

🟢

If Mitigated

With proper application sandboxing and user permission controls, impact would be limited to non-critical data.

🌐 Internet-Facing: LOW - This requires local application execution rather than remote exploitation.
🏢 Internal Only: MEDIUM - Malicious applications could be installed internally and exploit this vulnerability.

🎯 Exploit Status

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

Exploitation requires user to install/run a malicious application. No public exploit details available.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: macOS Tahoe 26.2, Safari 26.2

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

Restart Required: Yes

Instructions:

1. Open System Settings > General > Software Update. 2. Install macOS Tahoe 26.2 update. 3. For Safari, update through App Store or System Settings. 4. Restart system after installation.

🔧 Temporary Workarounds

Application Sandboxing Enforcement

all

Enable strict application sandboxing to limit data access

sudo spctl --master-enable
sudo spctl --enable

Gatekeeper Settings

all

Configure Gatekeeper to only allow apps from App Store and identified developers

sudo spctl --status
sudo spctl --enable --label "Mac App Store"
sudo spctl --enable --label "Developer ID"

🧯 If You Can't Patch

  • Implement application allowlisting to prevent unauthorized applications from running
  • Enable full disk encryption and restrict user permissions to sensitive data directories

🔍 How to Verify

Check if Vulnerable:

Check macOS version: sw_vers -productVersion. Check Safari version: Safari > About Safari. If versions are earlier than 26.2, system is vulnerable.

Check Version:

macOS: sw_vers -productVersion. Safari: defaults read /Applications/Safari.app/Contents/Info.plist CFBundleShortVersionString

Verify Fix Applied:

Verify macOS version is 26.2 or later and Safari version is 26.2 or later using same commands.

📡 Detection & Monitoring

Log Indicators:

  • Unusual application access to protected directories in Unified Logs
  • Console.app entries showing permission denials or unusual file access patterns

Network Indicators:

  • Not applicable - local vulnerability

SIEM Query:

source="macos" AND (event="file_access" OR event="permission_denied") AND (path CONTAINS "/Users/" OR path CONTAINS "/Library/")
