CVE-2025-43230 is a medium-severity vulnerability affecting Apple iPadOS and related Apple operating systems including watchOS, visionOS, iOS, macOS Sequoia, and tvOS. The vulnerability arises from insufficient permission checks within the affected Apple platforms, allowing a malicious app to potentially access user-sensitive data without requiring user interaction or authentication. The weakness is categorized under CWE-863, which relates to improper authorization, indicating that the app could bypass intended access controls. The vulnerability has a CVSS v3.1 base score of 4.0, reflecting a low attack vector (local access required), low complexity, no privileges required, and no user interaction needed. The impact is limited to confidentiality, with no direct effect on integrity or availability. The issue has been addressed by Apple in updates iPadOS 17.7.9, watchOS 11.6, visionOS 2.6, iOS 18.6, macOS Sequoia 15.6, and tvOS 18.6, which implement additional permission checks to prevent unauthorized data access. No known exploits are currently reported in the wild, and the affected versions are unspecified but presumably all versions prior to the patched releases. This vulnerability highlights the importance of strict permission enforcement in mobile and embedded operating systems to protect sensitive user data from unauthorized app access.

For European organizations, this vulnerability could lead to unauthorized disclosure of sensitive user data on Apple devices used within corporate environments, particularly iPads and other Apple devices running the affected OS versions. This could include exposure of personal information, corporate emails, or confidential documents stored or accessed via these devices. While the attack requires local access (i.e., installation of a malicious app), the lack of required user interaction or privileges lowers the barrier for exploitation once the app is installed. Organizations relying heavily on Apple devices for mobile productivity, especially in sectors handling sensitive data such as finance, healthcare, and government, may face risks of data leakage or privacy breaches. The impact is primarily on confidentiality, which can lead to compliance issues under GDPR and other data protection regulations in Europe, potentially resulting in legal and reputational consequences. However, the absence of known exploits and the medium severity score suggest the threat is moderate but should be addressed promptly to maintain security posture.

European organizations should prioritize updating all Apple devices to the patched OS versions as soon as possible to remediate this vulnerability. Specifically, ensure deployment of iPadOS 17.7.9 or later, iOS 18.6 or later, watchOS 11.6 or later, visionOS 2.6 or later, macOS Sequoia 15.6 or later, and tvOS 18.6 or later. Additionally, organizations should enforce strict app installation policies, such as restricting app installations to trusted sources (e.g., Apple App Store only) and employing Mobile Device Management (MDM) solutions to control app permissions and monitor installed applications. Regular audits of installed apps and permissions can help detect unauthorized or suspicious apps that might exploit this vulnerability. User awareness training should emphasize the risks of installing untrusted apps. For highly sensitive environments, consider implementing endpoint protection solutions capable of detecting anomalous app behavior. Finally, maintain up-to-date backups and incident response plans to quickly address any potential data exposure incidents.
