CVE-2025-43301 is a privacy-related vulnerability identified in Apple macOS systems, specifically involving the Notification Center's handling of contact information within notifications. The root cause lies in inadequate redaction of sensitive private data in log entries, which could allow a malicious or untrusted application to access contact details associated with notifications displayed in the Notification Center. This vulnerability affects multiple versions of macOS prior to the patched releases: macOS Sequoia 15.7, Sonoma 14.8, and Tahoe 26. The issue is classified under CWE-359 (Exposure of Private Information Through Log Files), highlighting the risk of sensitive data leakage via system logs. The CVSS v3.1 base score is 3.3, indicating a low severity level. The vector string (AV:L/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N) shows that exploitation requires local access (local attack vector), low attack complexity, no privileges, and user interaction, with impact limited to confidentiality (disclosure of contact info) without affecting integrity or availability. No known exploits have been reported in the wild, suggesting limited active threat but a potential privacy risk if exploited. The vulnerability was publicly disclosed in September 2025, with Apple addressing it through improved private data redaction in the specified macOS versions.

The primary impact of CVE-2025-43301 is the unauthorized disclosure of contact information related to notifications in the macOS Notification Center. This could lead to privacy violations, such as exposure of personal or professional contact details to malicious applications. While the vulnerability does not compromise system integrity or availability, the leakage of contact data could facilitate targeted phishing, social engineering, or identity theft attacks. For organizations, especially those handling sensitive communications or operating in regulated industries, this could result in compliance issues and reputational damage. The requirement for local access and user interaction limits the scope of exploitation, reducing the risk of widespread automated attacks. However, in environments where multiple users share systems or where untrusted applications are installed, the risk is more pronounced. Since no exploits are known in the wild, the immediate threat is low, but the vulnerability should be addressed to prevent potential future abuse.

To mitigate CVE-2025-43301, organizations and users should promptly update affected macOS systems to the patched versions: macOS Sequoia 15.7, Sonoma 14.8, or Tahoe 26. Beyond patching, organizations should enforce strict application installation policies to limit untrusted or unnecessary apps that could exploit local vulnerabilities. Employ endpoint protection solutions capable of monitoring and restricting app behaviors related to accessing notification data or logs. Regularly audit and monitor system logs and notification data access patterns for unusual activity. Educate users about the risks of interacting with untrusted applications and the importance of applying system updates promptly. For environments with shared devices, implement user account restrictions and consider disabling or limiting Notification Center features if feasible. Finally, review privacy settings related to notifications and app permissions to minimize exposure of sensitive contact information.
