An authorization issue was addressed with improved access control. This issue is fixed in macOS Golden Gate 27, macOS Sequoia 15.8. An app may be able to access sensitive user data.

The remote host is running a version of macOS / Mac OS X that is 27.x prior to the full release of 27.0. It is, therefore, affected by multiple vulnerabilities:

  - A validation issue existed in the entitlement verification. This issue was addressed with improved     validation of the process entitlement. This issue is fixed in macOS Golden Gate 27, macOS Sequoia 15.8,     macOS Tahoe 26.7. A malicious app may be able to break out of its sandbox. (CVE-2026-65381)

  - An authentication issue was addressed with improved state management. This issue is fixed in macOS Golden     Gate 27, macOS Sequoia 15.7.9, macOS Sonoma 14.8.9, macOS Tahoe 26.6.1, macOS Tahoe 26.7. An attacker on     the network may be able to authenticate to Screen Sharing without valid credentials. (CVE-2026-65400)

  - An out-of-bounds write issue was addressed with improved bounds checking. This issue is fixed in iOS 26.7     and iPadOS 26.7, iOS 27 and iPadOS 27, macOS Golden Gate 27, macOS Sequoia 15.8, macOS Tahoe 26.7, tvOS     27, visionOS 27, watchOS 27. A remote attacker may be able to cause unexpected app termination or     arbitrary code execution. (CVE-2026-65414)

Note that Nessus has not tested for these issues but has instead relied only on the operating system's self-reported version number.

The remote host is running a version of macOS / Mac OS X that is 15.x prior to 15.8. It is, therefore, affected by multiple vulnerabilities:

  - A validation issue existed in the entitlement verification. This issue was addressed with improved     validation of the process entitlement. This issue is fixed in macOS Golden Gate 27, macOS Sequoia 15.8,     macOS Tahoe 26.7. A malicious app may be able to break out of its sandbox. (CVE-2026-65381)

  - A heap-based buffer overflow vulnerability was found in Samba within the GSSAPI unwrap_des() and     unwrap_des3() routines of Heimdal. The DES and Triple-DES decryption routines in the Heimdal GSSAPI     library allow a length-limited write buffer overflow on malloc() allocated memory when presented with a     maliciously small packet. This flaw allows a remote user to send specially crafted malicious data to the     application, possibly resulting in a denial of service (DoS) attack. (CVE-2022-3437)

  - An authentication issue was addressed with improved state management. This issue is fixed in iOS 27 and     iPadOS 27, macOS Golden Gate 27, macOS Sequoia 15.8, macOS Tahoe 26.7, visionOS 27. An app may be able to     use the Sign In With Apple authentication flow to access the user's Apple Account. (CVE-2026-20683)

  - A logic issue was addressed with improved checks. This issue is fixed in macOS Golden Gate 27, macOS     Sequoia 15.8, macOS Tahoe 26.6, macOS Tahoe 26.7. An app may bypass Gatekeeper checks. (CVE-2026-28899)

  - A permissions issue was addressed with additional restrictions. This issue is fixed in macOS Tahoe 26.5.
    An app may be able to access protected user data. (CVE-2026-28930)
