Overview
Today, we are discussing a critical vulnerability, CVE-2025-43253, that has been identified in macOS Sequoia 15.6 and macOS Sonoma 14.7.7. As a cybersecurity specialist, it’s critical to understand the significance of this vulnerability given its potential for system compromise or data leakage. This vulnerability allows a malicious app to launch arbitrary binaries on a trusted device, thereby undermining system security and potentially exposing sensitive information.
The severity of this vulnerability, rated 9.8 on the Common Vulnerability Scoring System (CVSS), makes it a top priority for security teams to address. The high score is indicative of the potential damage a successful exploit could cause, including, but not limited to, data theft, system compromise, and even a full-scale breach.

How the Exploit Works
The exploit takes advantage of a lack of proper input validation in the affected macOS versions. An attacker could craft a malicious application that, when executed, launches arbitrary binaries on the system. These binaries could contain malicious code capable of compromising the system or exfiltrating data. Given that no privileges are required for this exploit, even a standard user could unknowingly trigger it.
Conceptual Example Code
Here is a conceptual example of how the vulnerability might be exploited. This is not a real exploit code but is provided to illustrate the potential danger of the vulnerability.
$ malicious_app --execute arbitrary_binaryIn this conceptual example, a malicious app executes an arbitrary binary, possibly containing harmful commands or scripts. This could lead to a wide range of unwanted activities, including system compromise or data exfiltration.
This vulnerability is a serious security concern, and immediate action should be taken to mitigate its impact. The most effective mitigation is to apply the vendor-supplied patch. As a temporary measure, a web application firewall (WAF) or intrusion detection system (IDS) could be used to detect and block any unusual or malicious activities.
