CVE-2024-44195 is a logic vulnerability in Apple macOS that allows an application to read arbitrary files on the system without requiring privileges or user interaction. The root cause is an improper validation of file pathnames (CWE-22), which enables an attacker-controlled app to bypass intended access restrictions and access sensitive files. This flaw affects macOS versions before Sequoia 15.1, where Apple has implemented improved validation to address the issue. The vulnerability has a CVSS 3.1 base score of 7.5, indicating high severity, with an attack vector over the network, low attack complexity, no privileges required, and no user interaction needed. The impact is primarily on confidentiality, as attackers can read sensitive data, but it does not affect integrity or availability. No public exploits have been reported yet, but the vulnerability's characteristics suggest it could be exploited by malicious apps distributed through various means. The vulnerability is significant because it undermines macOS's security model by allowing unauthorized file access, potentially exposing user data, credentials, or system files. Organizations relying on macOS for critical operations should be aware of this risk and apply the security update promptly.

The primary impact of CVE-2024-44195 is unauthorized disclosure of sensitive information due to arbitrary file read capabilities by unprivileged applications. This can lead to exposure of confidential user data, system configuration files, credentials, or other sensitive information stored on macOS devices. Such data leakage can facilitate further attacks, including identity theft, espionage, or lateral movement within networks. Since the vulnerability does not affect integrity or availability, it does not directly enable data modification or denial of service. However, the breach of confidentiality alone can have severe consequences for organizations, especially those handling sensitive or regulated data. The ease of exploitation—requiring no privileges or user interaction—raises the risk of widespread abuse, particularly in environments where macOS devices are used extensively. This vulnerability could be leveraged by attackers to gain footholds or gather intelligence in corporate, government, or personal computing environments.

To mitigate CVE-2024-44195, organizations should immediately update all affected macOS systems to version Sequoia 15.1 or later, where the vulnerability is fixed with improved validation logic. Until patching is complete, restrict installation of untrusted or unsigned applications through macOS Gatekeeper and enforce strict application whitelisting policies. Employ endpoint detection and response (EDR) solutions to monitor for suspicious file access patterns indicative of exploitation attempts. Limit user permissions to reduce the risk of malicious app installation. Conduct regular audits of installed applications and remove any that are unnecessary or untrusted. Educate users about the risks of installing software from unverified sources. Additionally, implement network segmentation to isolate critical macOS systems and reduce exposure. Maintain up-to-date backups to mitigate potential follow-on impacts from data exposure or subsequent attacks.
