CVE-2026-28880 is a permissions-related vulnerability affecting Apple’s iOS, iPadOS, macOS, and visionOS platforms. The flaw allows an unprivileged application to enumerate the list of installed applications on a user’s device, violating user privacy and potentially aiding attackers in reconnaissance. This is due to insufficient permission enforcement, categorized under CWE-284 (Improper Access Control). The vulnerability is exploitable remotely without requiring user interaction or elevated privileges, increasing its risk profile. Apple has released patches in iOS 18.7.7, iPadOS 18.7.7, macOS Sequoia 15.7.5, Sonoma 14.8.5, Tahoe 26.4, and visionOS 26.4 to add stricter permission checks and prevent unauthorized app enumeration. Although no active exploits have been reported, the ability to gather installed app information can facilitate targeted attacks, phishing, or privacy invasions. The CVSS v3.1 score of 6.5 reflects a medium severity, with low complexity of attack and no required privileges or user interaction, but limited impact on confidentiality and availability. This vulnerability highlights the importance of robust permission models in mobile and desktop operating systems to protect user data and privacy.

The primary impact of CVE-2026-28880 is on user privacy and information confidentiality. By allowing an attacker to enumerate installed applications, malicious actors can profile users’ device configurations, identify security software or sensitive apps, and tailor subsequent attacks such as phishing, social engineering, or exploitation of known vulnerabilities in specific apps. While the vulnerability does not directly compromise data integrity or availability, it facilitates reconnaissance that can lead to more severe attacks. Organizations relying on Apple devices, especially those in sensitive sectors like finance, healthcare, or government, may face increased risk of targeted attacks if devices are unpatched. Additionally, the exposure of installed app lists can violate privacy policies and regulatory compliance requirements related to user data protection. The vulnerability’s ease of exploitation without user interaction or privileges increases the attack surface, making it a significant concern for enterprise and personal users alike.

To mitigate CVE-2026-28880, organizations and users should promptly apply the security updates released by Apple for iOS 18.7.7, iPadOS 18.7.7, macOS Sequoia 15.7.5, Sonoma 14.8.5, Tahoe 26.4, and visionOS 26.4. Beyond patching, administrators should enforce strict app installation policies, limiting apps to those from trusted sources and using Mobile Device Management (MDM) solutions to control app permissions. Monitoring network traffic for unusual app enumeration attempts can help detect exploitation attempts. Developers should review their apps to ensure they do not inadvertently expose installed app information through APIs or inter-process communication. User education on the risks of installing untrusted apps and the importance of timely updates is also critical. Finally, organizations should integrate this vulnerability into their threat modeling and incident response plans to quickly address any exploitation attempts.
