What is CVE-2025-31258?

CVE-2025-31258 is a vulnerability in macOS Sequoia, an operating system developed by Apple, aimed at providing a secure and user-friendly computing environment. This particular vulnerability is categorized as a "sandbox escape," meaning it allows malicious applications to break out of their restricted environments—a significant security measure intended to isolate potentially harmful software from affecting the broader system.

The presence of this vulnerability poses critical risks to organizations as it could enable attackers to exploit apps with limited access rights. By breaking out of their designated sandbox, these apps may access sensitive system resources, data, and functionalities that should otherwise be protected, leading to potential unauthorized data loss, system integrity issues, or compromise of confidential operational processes.

Potential impact of CVE-2025-31258

Unauthorized Access to Sensitive Data: The vulnerability can allow malicious applications to gain access to user data and system resources that they are not normally permitted to interact with. This unauthorized access can lead to data breaches, exposing sensitive information to attackers.
System Integrity Compromise: By escaping the sandbox, an application can modify or damage system configurations and files, leading to system instability and increased vulnerability to further attacks. This could also impact critical business operations depending on the integrity of the operating system.
Elevation of Privileges for Attackers: The ability to break out of a sandbox may allow attackers to execute code with elevated privileges, enabling them to perform malicious actions that can compromise the integrity of the entire system or network, potentially facilitating broader attacks, including data exfiltration and deployment of ransomware.

Affected Version(s)

macOS < 15.5

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
