CVE-2025-24101 is a vulnerability identified in Apple macOS that arises from improper redaction of sensitive user information. This flaw allows an application, potentially without elevated privileges, to access sensitive data that should have been obscured or protected. The vulnerability requires user interaction, such as running or installing the malicious app, but does not require prior authentication or elevated privileges, increasing its risk profile. The issue was addressed in macOS Sequoia 15.3 by enhancing the mechanisms that redact sensitive information, thereby preventing unauthorized access. The vulnerability is categorized under CWE-922, which involves improper data redaction leading to exposure of confidential information. The CVSS v3.1 base score is 5.5, reflecting a medium severity level, with a vector indicating local attack vector (AV:L), low attack complexity (AC:L), no privileges required (PR:N), user interaction required (UI:R), unchanged scope (S:U), high confidentiality impact (C:H), and no impact on integrity or availability (I:N/A:N). No known exploits have been reported in the wild as of the publication date. This vulnerability primarily threatens the confidentiality of user data on affected macOS systems, potentially exposing sensitive personal or corporate information to malicious applications.

The primary impact of CVE-2025-24101 is the unauthorized disclosure of sensitive user data on macOS devices. This can lead to privacy violations, leakage of personally identifiable information (PII), corporate secrets, or other confidential data. Organizations relying on macOS for business operations, especially those handling sensitive or regulated data, may face compliance risks and reputational damage if this vulnerability is exploited. Although the vulnerability does not affect system integrity or availability, the exposure of sensitive data can facilitate further attacks such as social engineering, identity theft, or targeted intrusions. The requirement for user interaction limits the ease of exploitation but does not eliminate risk, as users may inadvertently run malicious applications. The absence of known exploits in the wild suggests limited current threat activity, but the medium severity score indicates that attackers could develop effective exploits. Enterprises with large macOS deployments, including government, finance, healthcare, and technology sectors, are particularly at risk due to the value of the data potentially exposed.

To mitigate CVE-2025-24101, organizations should prioritize updating all macOS devices to version Sequoia 15.3 or later, where the vulnerability has been addressed through improved data redaction. Beyond patching, organizations should implement application control policies to restrict the installation and execution of untrusted or unsigned applications, reducing the risk of malicious apps exploiting this flaw. User education is critical to minimize risky behaviors such as running unknown software or clicking on suspicious links that could trigger exploitation. Employ endpoint detection and response (EDR) solutions capable of monitoring for anomalous application behaviors that may indicate attempts to access sensitive data improperly. Additionally, enforce the principle of least privilege for user accounts and applications to limit the potential impact of any compromise. Regularly audit and monitor sensitive data access logs to detect unusual access patterns. Finally, maintain an up-to-date inventory of macOS devices and ensure timely deployment of security updates to reduce exposure windows.
