CVE-2026-33631

ClearanceKit · ClearanceKit for macOS

ClearanceKit for macOS contains a vulnerability in its file-system access event interception, potentially allowing bypass of per-process access policies.

Executive summary

A vulnerability in ClearanceKit on macOS could allow an attacker to bypass file-system access policies, leading to unauthorized data access or privilege escalation.

Vulnerability

ClearanceKit is designed to intercept file-system access events on macOS to enforce security policies. The vulnerability exists in the interception mechanism, which may fail to correctly identify or block unauthorized requests, allowing processes to access files they should be restricted from based on the defined security policy.

Business impact

This vulnerability is assigned a CVSS score of 8.7, indicating a High-severity risk. If exploited, it undermines the core security function of the software, potentially allowing malicious applications to access sensitive user data, configuration files, or system resources. This could lead to a total compromise of the endpoint's data confidentiality and integrity.

Remediation

Immediate Action: Update ClearanceKit to the latest version provided by the developer to ensure the file-system interception and policy enforcement engine is properly secured.

Proactive Monitoring: Monitor macOS system logs and Endpoint Detection and Response (EDR) alerts for unauthorized file access attempts or modifications to ClearanceKit configuration files.

Compensating Controls: Use macOS native security features, such as Transparency, Consent, and Control (TCC) and Sandbox profiles, to provide redundant layers of file-system protection.

Exploitation status

Public Exploit Available: false

Analyst recommendation

Security tools that fail to enforce their primary policies create a false sense of security. Organizations should prioritize the update of ClearanceKit across all macOS endpoints to ensure that file-system access remains strictly controlled and monitored.
