CVE-2026-47134
ClearanceKit intercepts file-system access events on macOS and enforces per-process access policies.
Overview
CVE-2026-47134 is a known-severity vulnerability. It was published on July 20, 2026.
Technical description
ClearanceKit intercepts file-system access events on macOS and enforces per-process access policies. The ECDSA private key used to sign the on-disk policy database (`/Library/Application Support/clearancekit/store.db`) is stored in the macOS System Keychain. The key was created via the two-step pattern `SecKeyCreateRandomKey` (in-memory) followed by `SecItemAdd(kSecValueRef:, kSecAttrAccess:)` (persist). Prior to version 5.0.10, for `kSecClassKey` items in the legacy System Keychain, `kSecAttrAccess` passed to `SecItemAdd` is silently ignored — the persisted key inherits no ACL restriction. The same access builder applied to `kSecClassGenericPassword` items correctly binds the ACL, making this bug specific to the EC key. The result is that any process running as root can use the key to produce valid signatures over arbitrary policy content. Version 5.0.10 fixes the issue. No known workarounds are available. Disabling the system extension and manually removing the System Keychain item l

How can CyberStrike help with CVE-2026-47134?
CyberStrike is an open-source, AI-augmented pentesting engine. Rather than flag a version number, it tests whether an issue like CVE-2026-47134 is actually reachable in your own applications and APIs, then verifies each finding before reporting it. That tells you if the weakness is a real, exploitable risk in your environment or a false positive you can safely deprioritize.
