The sandbox is a critical security mechanism in macOS that restricts what actions applications can perform and what system resources they can access, creating an isolated environment that helps protect the system from malicious software. “Another 1day practice: CVE-2025-31258 (patched in macOS 15.5) Escaped macOS sandbox, but partial,” wh1te4ever wrote on social platform X, sharing links to the exploit code repository and a demonstration video. However, just hours after the patch’s release, security researcher Seo Hyun-gyu (using the GitHub handle “wh1te4ever”) published a working PoC exploit demonstrating the vulnerability in action. The GitHub repository “CVE-2025-31258-PoC” contains an Xcode project demonstrating the vulnerability, labeled as a “1day practice” – referring to exploits developed after a patch is released but before most users have updated their systems. The flaw could allow malicious applications to break out of the macOS sandbox protection mechanism, potentially giving attackers access to sensitive system resources and user data. This vulnerability disclosure follows a trend of security researchers publishing “1day” exploits shortly after patches are released, highlighting the importance of prompt security updates. A proof-of-concept (PoC) exploit has been released for a recently patched vulnerability in Apple’s macOS operating system, tracked as CVE-2025-31258.
