How the CVE Works
CVE-2025-24226 is a critical vulnerability in Xcode versions prior to 16.3, allowing malicious apps to bypass privacy checks and access sensitive user data. The flaw stems from improper validation of app enments, enabling unauthorized access to private information stored in the system or other apps. Attackers can craft a malicious application that exploits weak enment checks, leading to data leaks such as keychain items, user credentials, or app-specific secrets. The vulnerability is rated critical due to its potential for widespread exploitation in software development environments.

- Attack Vector: Local
- Impact: High Confidentiality
Commands:
Check Xcode version xcodebuild -version Verify enments in an app codesign -d --enments - /path/to/app Monitor enment access log stream --predicate 'eventMessage contains "enment"'
Code Snippet (Enment Check Bypass):
let task = Process() task.launchPath = "/usr/bin/defaults" task.arguments = [bash] task.launch()
Mitigation Code:
// Enforce strict enment checks
func validateEnments() -> Bool {
guard let ents = Bundle.main.infoDictionary?[bash] as? [bash] else { return false }
return ents[bash] as? Bool == true
}
