CVE-2025-31207 is a logic vulnerability identified in Apple’s iOS and iPadOS platforms that allows an application to enumerate the list of installed applications on a user's device. This issue arises from inadequate validation and checks within the operating system's app management logic, permitting unauthorized apps to access information about other installed apps. Such enumeration can reveal sensitive user behavior patterns, installed security tools, or corporate applications, potentially aiding targeted attacks or privacy violations. The vulnerability affects all versions before iOS and iPadOS 18.5, where Apple has implemented improved checks to prevent unauthorized app enumeration. The vulnerability is classified under CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor). The CVSS v3.1 base score is 7.7 (high), with vector AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H, indicating local attack vector, low attack complexity, no privileges or user interaction required, unchanged scope, high confidentiality impact, no integrity impact, and high availability impact. Although no known exploits are reported in the wild, the ease of exploitation and sensitive data exposure make this a significant risk. The flaw could be leveraged by malicious apps to profile users or bypass security controls by detecting installed security or enterprise apps. The patch is included in iOS and iPadOS 18.5, and users should upgrade promptly.

The primary impact of CVE-2025-31207 is the unauthorized disclosure of sensitive information about installed applications on iOS and iPadOS devices. This can compromise user privacy by revealing personal or corporate app usage patterns. For organizations, this information leakage can facilitate targeted attacks, social engineering, or reconnaissance by adversaries seeking to exploit known vulnerabilities in specific apps. The high confidentiality impact combined with the potential to disrupt availability (as indicated by the CVSS vector) suggests that attackers might also leverage this enumeration to interfere with device operations or app functionality indirectly. Since no privileges or user interaction are required, any malicious app installed on a device can exploit this vulnerability, increasing the attack surface. This is particularly concerning for enterprises using iOS/iPadOS devices for sensitive communications or operations. The lack of known exploits in the wild currently reduces immediate risk but does not eliminate the threat, especially as attackers may develop exploits rapidly once the vulnerability is public. Failure to patch could lead to privacy breaches, targeted malware deployment, or disruption of critical mobile workflows.

To mitigate CVE-2025-31207, organizations and users should immediately update all affected devices to iOS and iPadOS version 18.5 or later, where the vulnerability has been fixed with improved logic checks. Beyond patching, organizations should enforce strict app vetting policies to prevent installation of untrusted or potentially malicious applications that could exploit this flaw. Mobile Device Management (MDM) solutions should be configured to restrict app installation sources and monitor app behavior for suspicious enumeration activities. Employing app sandboxing and runtime protections can further limit the ability of apps to gather unauthorized information. Security teams should audit installed apps regularly to detect any unauthorized or suspicious applications. Additionally, educating users about the risks of installing apps from untrusted sources can reduce exposure. For high-security environments, consider deploying endpoint detection and response (EDR) tools tailored for iOS/iPadOS to detect anomalous app behaviors. Finally, monitor threat intelligence feeds for any emerging exploits targeting this vulnerability to respond promptly.
