IdentifiersCVE-2026-28880CWE-863

CVE-2026-28880 is a permissions issue in Apple iCloud-related functionality that could allow a local app to enumerate a user's installed applications. Apple states the issue was addressed with additional restrictions. The vulnerability affects multiple Apple operating systems, including iOS 18.7.7 and iPadOS 18.7.7, iOS 26.4 and iPadOS 26.4, macOS Sequoia 15.7.5, macOS Sonoma 14.8.5, macOS Tahoe 26.4, and visionOS 26.4.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation allows an app to determine which applications are installed on the target device. This is a privacy impact that can expose user profiling information, reveal use of sensitive apps, and provide reconnaissance data that may support follow-on targeting, social engineering, or tailored exploitation. No evidence in the provided content indicates direct code execution, privilege escalation, or arbitrary data modification from this issue alone.

Mitigation

If you can’t patch tonight, do this now.

Until patched, reduce exposure by limiting installation and execution of untrusted or unnecessary apps, especially on affected Apple platforms. Enterprise controls such as application allowlisting, MDM-enforced software restrictions, and prompt deployment of Apple security updates can reduce risk. The provided content does not describe any vendor-specified workaround other than installing the fixed releases.

Remediation

Patch, then assume compromise.

Apply the vendor fixes provided by Apple. Apple states the issue is fixed in iOS 18.7.7 and iPadOS 18.7.7, iOS 26.4 and iPadOS 26.4, macOS Sequoia 15.7.5, macOS Sonoma 14.8.5, macOS Tahoe 26.4, and visionOS 26.4.
