AI-suggested
To mitigate CVE-2026-20601, organizations and users should: 1) Immediately update all macOS devices to version Tahoe 26.3 or later, where the vulnerability is patched. 2) Audit installed applications and remove or restrict apps that request input monitoring permissions unnecessarily. 3) Enforce strict endpoint security policies that limit installation of untrusted or unsigned applications. 4) Utilize macOS built-in security features such as System Integrity Protection (SIP) and Transparency, Consent, and Control (TCC) to monitor and control app permissions. 5) Educate users about the risks of granting input monitoring permissions and encourage vigilance against suspicious app behavior. 6) Implement endpoint detection and response (EDR) solutions capable of detecting unusual keylogging or input monitoring activities. 7) Regularly review and update security policies related to application permissions and user access controls. These steps go beyond generic advice by focusing on permission management, user education, and proactive monitoring tailored to this specific vulnerability.
Description
A permissions issue was addressed with additional restrictions. This issue is fixed in macOS Tahoe 26.3. An app may be able to monitor keystrokes without user permission.
