CVE-2025-43313 is a logic-based vulnerability identified in Apple macOS, where a flaw in the system's access control logic allows an application to bypass intended restrictions and access sensitive user data. The vulnerability stems from improper enforcement of security boundaries within the operating system, enabling an app to escalate privileges or circumvent sandboxing mechanisms designed to protect user information. Apple has released fixes in macOS Ventura 13.7.7, Sonoma 14.7.7, and Sequoia 15.6 to address this issue by implementing improved restrictions that close the logic gap. The affected versions prior to these patches are unspecified, but it is implied that multiple recent macOS releases are vulnerable. No public exploits have been observed in the wild, indicating that active exploitation is not currently widespread. However, the potential for sensitive data exposure remains significant, especially if a malicious or compromised app is installed on a target system. The vulnerability primarily impacts the confidentiality of user data, as unauthorized access could lead to leakage of personal or corporate information. Since the flaw is logic-based, exploitation may not require complex technical skills but does require the app to be present on the device, possibly through social engineering or supply chain compromise. The absence of a CVSS score necessitates an assessment based on impact and exploitability factors.

For European organizations, this vulnerability poses a risk to the confidentiality of sensitive user and corporate data on macOS devices. Organizations relying on Apple hardware for business operations, especially those handling personal data under GDPR, could face data breaches leading to regulatory penalties and reputational damage. The exposure of sensitive data could facilitate further attacks such as identity theft, corporate espionage, or unauthorized access to internal systems. Since macOS is widely used in sectors like finance, technology, and creative industries across Europe, the impact could be substantial if exploited. The lack of known exploits reduces immediate risk, but the potential for future exploitation remains, especially in targeted attacks. Organizations with remote or hybrid workforces using macOS devices are particularly vulnerable if patch management is not promptly enforced. Additionally, the breach of confidentiality could undermine trust in digital services and complicate compliance with data protection regulations.

European organizations should immediately verify the macOS versions deployed across their environments and prioritize upgrading to macOS Ventura 13.7.7, Sonoma 14.7.7, or Sequoia 15.6 where applicable. Implement strict application control policies to limit the installation of untrusted or unsigned apps, reducing the risk of malicious apps exploiting this vulnerability. Employ endpoint detection and response (EDR) solutions capable of monitoring unusual app behaviors indicative of unauthorized data access. Regularly audit installed applications and remove any unnecessary or suspicious software. Enforce least privilege principles for user accounts and applications to minimize potential damage from compromised apps. Educate users about the risks of installing unverified applications and phishing tactics that could lead to app compromise. Maintain robust backup and incident response plans to quickly address any data exposure incidents. Collaborate with Apple support channels for timely updates and advisories related to this vulnerability.
