CVE-2026-40599: CWE-863: Incorrect Authorization in craigjbass clearancekit
ClearanceKit intercepts file-system access events on macOS and enforces per-process access policies. Prior to 5.0.5, ClearanceKit incorrectly treats a process with an empty Team ID and a non-empty Signing ID as an Apple platform binary. This bug allows a malicious software to impersonate an apple process in the global allowlist, and access all protected files. This vulnerability is fixed in 5.0.5.
AI Analysis
Technical Summary
ClearanceKit, a macOS tool enforcing per-process file access policies, incorrectly treats processes that have an empty Team ID and a non-empty Signing ID as Apple platform binaries before version 5.0.5. This incorrect authorization (CWE-863) enables malicious software to bypass intended access controls by impersonating Apple processes listed in the global allowlist, thereby gaining unauthorized access to protected files. The issue is resolved in ClearanceKit 5.0.5.
Potential Impact
Exploitation of this vulnerability allows a local process with limited privileges to impersonate an Apple platform binary, bypassing ClearanceKit's access controls and accessing all protected files on the system. This could lead to unauthorized data access and potential compromise of sensitive information.
Mitigation Recommendations
This vulnerability is fixed in ClearanceKit version 5.0.5. Users should upgrade to version 5.0.5 or later to remediate this issue. No other mitigation or workaround is indicated.
