ClearanceKit: opfilter policy bypass via exchangedata and clone operations_CVE-2026-33632

{
    "lastseen": "",
    "description": "ClearanceKit intercepts file-system access events on macOS and enforces per-process access policies. Prior to version 4.2.4, two file operation event types \u2014 ES_EVENT_TYPE_AUTH_EXCHANGEDATA and ES_EVENT_TYPE_AUTH_CLONE \u2014 were not intercepted by ClearanceKit's opfilter system extension, allowing local processes to bypass file access policies. Commit 6181c4a patches the vulnerability by subscribing to both event types and routing them through the existing policy evaluator. Users must upgrade to v4.2.4 or later and reactivate the system extension.",
