CVE-2025-31262 is a permissions vulnerability identified in Apple’s iOS, iPadOS, and other related operating systems such as macOS Sequoia, tvOS, visionOS, and watchOS. The issue stems from insufficient restrictions on app permissions that allow an app operating with limited privileges (PR:L) to modify protected parts of the file system, which are normally inaccessible to third-party applications. This vulnerability does not require user interaction (UI:N) and has a low attack complexity (AC:L), but the attacker must have local access (AV:L) to the device. The scope of the vulnerability is unchanged (S:U), meaning it affects only the privileges of the compromised component without extending to other components. The impact is primarily on integrity (I:H), as unauthorized modification of protected files can lead to persistent unauthorized changes, potential privilege escalation, or tampering with system files. Confidentiality and availability impacts are rated none (C:N, A:N). Apple has addressed this issue by implementing additional restrictions in iOS 18.3 and corresponding updates for other Apple OS versions. The vulnerability is tracked under CWE-732, which relates to permissions issues. No public exploits are known at this time, but the vulnerability poses a risk if exploited by malicious apps or attackers with local access.

The primary impact of CVE-2025-31262 is on the integrity of Apple devices running vulnerable OS versions. An attacker with limited privileges on a device could modify protected system files, potentially enabling persistent unauthorized changes, tampering with system behavior, or facilitating privilege escalation. This could undermine system trustworthiness and security controls. Although confidentiality and availability are not directly impacted, the integrity compromise could indirectly lead to further attacks or data manipulation. Organizations relying on Apple mobile devices for sensitive operations, including enterprises, government agencies, and critical infrastructure sectors, may face increased risk of targeted attacks or malware persistence. The requirement for local access limits remote exploitation, but insider threats or compromised devices remain a concern. The absence of known exploits reduces immediate risk but does not eliminate the potential for future attacks. Prompt patching is essential to prevent exploitation and maintain device security.

Organizations and users should promptly update affected Apple devices to iOS 18.3, iPadOS 18.3, macOS Sequoia 15.3, tvOS 18.3, visionOS 2.3, watchOS 11.3, or later versions where the vulnerability is fixed. Beyond patching, implement strict app vetting policies to limit installation of untrusted or unnecessary applications, reducing the risk of malicious apps exploiting this vulnerability. Employ mobile device management (MDM) solutions to enforce security policies and restrict app permissions. Regularly audit device configurations and installed apps to detect anomalies or unauthorized modifications. Educate users about the risks of installing apps from unverified sources and the importance of keeping devices updated. For high-security environments, consider additional endpoint protection and monitoring to detect suspicious file system changes. Maintain backups and incident response plans to quickly recover from potential integrity breaches.
