CVE-2025-43288 is a vulnerability in Apple macOS that allows an application to bypass Privacy preferences by exploiting inadequate validation of symbolic links (symlinks). Privacy preferences in macOS control access to sensitive user data and system resources, such as location services, camera, microphone, and files. The vulnerability arises because the system does not properly validate symlinks, enabling a malicious app to redirect access checks and circumvent privacy restrictions. This can lead to unauthorized access or modification of protected data, impacting the integrity of user privacy controls. The issue is classified under CWE-59, which pertains to improper handling of symbolic links that can lead to security bypasses. The vulnerability affects macOS versions prior to Sequoia 15.7 and Tahoe 26, where Apple has implemented improved symlink validation to address the flaw. Exploitation requires local access and some user interaction, such as running a malicious app, but does not require prior authentication or elevated privileges. The CVSS v3.1 base score is 5.5, reflecting a medium severity with local attack vector, low attack complexity, no privileges required, but user interaction needed. No known exploits have been reported in the wild as of now. The vulnerability's impact is primarily on the integrity of privacy controls, potentially allowing unauthorized data access or manipulation by malicious applications.

The primary impact of CVE-2025-43288 is the potential unauthorized bypass of macOS Privacy preferences, which can lead to malicious applications accessing or modifying sensitive user data without consent. This undermines user trust and the confidentiality of personal information such as location, camera, microphone, and files. For organizations, this could result in data leakage, intellectual property theft, or exposure of sensitive communications. The integrity of privacy controls is compromised, which may facilitate further attacks or persistent footholds by adversaries. Although the vulnerability does not directly affect system availability, the breach of privacy controls can have significant reputational and compliance consequences, especially for sectors handling sensitive data like finance, healthcare, and government. Since exploitation requires local access and user interaction, the risk is higher in environments where users may install untrusted software or where endpoint security is weak. The lack of known exploits in the wild reduces immediate risk but does not eliminate the threat, as attackers may develop exploits once the vulnerability is publicly known.

Organizations and users should promptly update affected macOS systems to versions Sequoia 15.7 or Tahoe 26, where Apple has fixed the vulnerability by improving symlink validation. Until patches are applied, restrict installation of untrusted or unsigned applications to reduce the risk of local exploitation. Employ endpoint protection solutions that monitor and block suspicious behaviors related to symbolic link manipulation. Educate users about the risks of running unknown applications and the importance of maintaining updated software. Implement application whitelisting and use macOS’s built-in privacy and security features to limit app permissions. Regularly audit privacy preference settings and monitor for unusual access patterns to sensitive resources. For organizations, consider deploying Mobile Device Management (MDM) solutions to enforce patch management and security policies. Finally, maintain robust backup and incident response plans to quickly recover from potential breaches resulting from exploitation of this vulnerability.
