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

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - The issue was addressed with improved memory handling. This issue is fixed in Safari 26.3, iOS 18.7.5 and     iPadOS 18.7.5, iOS 26.3 and iPadOS 26.3, macOS Tahoe 26.3, visionOS 26.3. A remote attacker may be able to     cause a denial-of-service. (CVE-2026-20652)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote host is running a version of macOS / Mac OS X that is 26.x prior to 26.3. It is, therefore, affected by multiple vulnerabilities:

  - A race condition was addressed with improved handling of symbolic links. This issue is fixed in macOS     Tahoe 26.3, macOS Sonoma 14.8.4, iOS 18.7.5 and iPadOS 18.7.5, visionOS 26.3, iOS 26.3 and iPadOS 26.3. A     shortcut may be able to bypass sandbox restrictions. (CVE-2026-20677)

  - A path handling issue was addressed with improved logic. This issue is fixed in macOS Tahoe 26.3, macOS     Sonoma 14.8.4, iOS 18.7.5 and iPadOS 18.7.5, visionOS 26.3, iOS 26.3 and iPadOS 26.3, Safari 26.3. A     remote user may be able to write arbitrary files. (CVE-2026-20660)

  - libexpat in Expat before 2.7.2 allows attackers to trigger large dynamic memory allocations via a small     document that is submitted for parsing. (CVE-2025-59375)

  - A permissions issue was addressed with additional restrictions. This issue is fixed in macOS Tahoe 26.3.
    An app may be able to monitor keystrokes without user permission. (CVE-2026-20601)

  - The issue was addressed with improved handling of caches. This issue is fixed in macOS Sequoia 15.7.4,     macOS Tahoe 26.3, macOS Sonoma 14.8.4. An app may be able to cause a denial-of-service. (CVE-2026-20602)

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

The version of Apple iOS running on the mobile device is prior to 26.3. It is, therefore, affected by multiple vulnerabilities.

The version of Apple iOS running on the mobile device is prior to 18.7.5. It is, therefore, affected by multiple vulnerabilities.
