Worst Case
Malicious applications could extract passwords, authentication tokens, personal identifiers, or other sensitive data from system logs, leading to credential theft or privacy violations.
Likely Case
Applications with legitimate access to system logs might inadvertently expose sensitive information, or malicious apps could harvest limited sensitive data from logs.
If Mitigated
With proper application sandboxing and least-privilege principles, exposure would be limited to non-sensitive log data only.
🎯 Exploit Status
Exploitation requires a malicious application to be installed and running on the target system. No public exploit code has been disclosed.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: macOS Ventura 13.7, macOS Sonoma 14.7, macOS Sequoia 15
