CVE-2025-46277 is a vulnerability identified in Apple’s iOS and iPadOS platforms, as well as macOS Tahoe and watchOS, where an application may gain unauthorized access to a user's Safari browsing history. The root cause is a logging issue related to insufficient data redaction, which allowed sensitive browsing data to be exposed to apps with certain privileges. This vulnerability falls under CWE-532 (Information Exposure Through Log Files). The issue was addressed by Apple in version 26.2 of the affected operating systems by improving data redaction mechanisms to prevent leakage of Safari history through logs. The CVSS 3.1 base score is 5.5, indicating a medium severity level. The attack vector is local (AV:L), meaning the attacker must have local access to the device, and the attack complexity is low (AC:L). Privileges required are low (PR:L), so an app with limited privileges can exploit this without user interaction (UI:N). The impact is high on confidentiality (C:H) but none on integrity (I:N) or availability (A:N). No known exploits have been reported in the wild, suggesting limited active exploitation currently. The vulnerability primarily threatens user privacy by exposing browsing history, which could be leveraged for profiling or targeted attacks. The affected versions are prior to 26.2 releases of iOS, iPadOS, macOS Tahoe, and watchOS. Organizations and users should apply the updates promptly to mitigate this risk.

The primary impact of CVE-2025-46277 is the unauthorized disclosure of sensitive user browsing history from Safari to potentially malicious or overly permissive apps. This breach of confidentiality can lead to privacy violations, user profiling, and targeted social engineering or phishing attacks. While the vulnerability does not affect system integrity or availability, the exposure of browsing data can undermine user trust and compliance with privacy regulations such as GDPR or CCPA. Organizations with employees using vulnerable Apple devices may face increased risk of insider threats or data leakage. The requirement for local access and low privileges means that attackers need to have some presence on the device, but no user interaction is needed, increasing the risk from malicious apps installed on the device. The absence of known exploits in the wild reduces immediate risk but does not eliminate the potential for future exploitation. Overall, the impact is significant for privacy-sensitive environments and users relying heavily on Safari for browsing.

To mitigate CVE-2025-46277, organizations and users should: 1) Immediately update all affected Apple devices (iOS, iPadOS, macOS Tahoe, watchOS) to version 26.2 or later where the vulnerability is patched. 2) Implement strict app vetting and permission management policies to limit installation of untrusted or unnecessary apps that could exploit local privileges. 3) Employ Mobile Device Management (MDM) solutions to enforce update compliance and restrict app capabilities. 4) Monitor device logs and app behavior for unusual access patterns to Safari data or logs. 5) Educate users about the risks of installing apps from untrusted sources and the importance of timely OS updates. 6) Consider disabling or limiting Safari history logging if feasible in sensitive environments until patches are applied. 7) Review and audit app permissions regularly to ensure minimal privilege principle is enforced. These steps go beyond generic advice by emphasizing proactive device management, user education, and monitoring tailored to this specific vulnerability.
