  • Critical Vulnerability in Apple Devices: App May Enumerate Installed Apps (CVE-2025-30426)

    Overview of CVE-2025-30426

    A critical vulnerability has been discovered in several Apple devices, including iOS, iPadOS, macOS, tvOS, and visionOS. Tracked as CVE-2025-30426, this issue allows an app to enumerate a user’s installed apps without proper authorization. This vulnerability has been addressed with additional entitlement checks in the latest updates: tvOS 18.4, iPadOS 17.7.6, iOS 18.4, macOS Sequoia 15.4, and visionOS 2.4.

    Details of the Vulnerability

    The issue arises when an app gains access to sensitive information about the apps installed on a device. By exploiting this vulnerability, an attacker can potentially gather a list of all installed apps, which could lead to unauthorized access to personal information and further exploitation of the system.

    This vulnerability has been classified as CWE-200, which refers to the exposure of sensitive information to an unauthorized actor. The flaw impacts a wide range of Apple devices, including iPhones, iPads, Macs, Apple TVs, and Vision Pro devices, running versions prior to the latest security patches.

    CVSS Score and Impact

    The CVSS v3.1 score for CVE-2025-30426 is a critical 9.8. The CVSS vector string for this vulnerability is: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H. This means:

    • Attack Vector (AV): Network – The vulnerability can be exploited remotely.
    • Attack Complexity (AC): Low – The exploit does not require complex conditions to execute.
    • Privileges Required (PR): None – No special privileges are needed to exploit the vulnerability.
    • User Interaction (UI): None – The vulnerability can be exploited without user interaction.
    • Confidentiality Impact (C): High – Sensitive user data can be accessed.
    • Integrity Impact (I): High – The attacker can alter system data.
    • Availability Impact (A): High – The attacker can cause disruptions to the system.

    Mitigation

    To mitigate the risks associated with CVE-2025-30426, Apple users are strongly advised to update their devices to the latest versions of iOS, iPadOS, tvOS, macOS, and visionOS. These updates address the vulnerability by adding additional entitlement checks to prevent unauthorized apps from enumerating installed apps.

  • CVE-2025-24263: Privacy Vulnerability in macOS

    CVE-2025-24263: Privacy Vulnerability in macOS

    A critical privacy vulnerability, CVE-2025-24263, has been identified in Apple’s macOS, affecting versions prior to macOS Sequoia 15.4. This flaw allows an attacker to observe unprotected user data, posing a significant security and privacy risk.

    Technical Details

    The CVE-2025-24263 vulnerability arises from a failure to properly protect sensitive user data. In older versions of macOS, an attacker could exploit this issue to observe data that should have been protected. This exposure of sensitive information can lead to unauthorized access, affecting both the confidentiality and integrity of user data.

    Apple addressed this vulnerability by relocating sensitive data to a protected location in macOS Sequoia 15.4. With this fix, the risk of unauthorized data exposure has been mitigated, enhancing overall system privacy.

    Impact and CVSS Score

    The CVSS score for CVE-2025-24263 is 9.8, marking it as a critical security vulnerability. The flaw can be exploited remotely over a network with low complexity, meaning attackers can exploit it without user interaction. This vulnerability significantly impacts the confidentiality and availability of user data, leaving systems open to unauthorized data access.

    Apple’s Response

    Apple quickly responded to this issue by releasing security updates in macOS Sequoia 15.4. These updates implement stronger protections for sensitive data, ensuring that malicious applications can no longer access unprotected user data.
