CVE-2025-5255

The Phoenix Code's configuration on macOS, specifically the presence of entitlements: "com.apple.security.cs.allow-dyld-environment-variables" and "com.apple.security.cs.disable-library-validation" allows for Dynamic Library (Dylib) injection. A local attacker with unprivileged access can use environment variables like DYLD_INSERT_LIBRARIES to successfully inject code in application's context and bypass Transparency, Consent, and Control (TCC). Acquired resource access is limited to previously granted permissions by the user. Access to other resources beyond granted-permissions requires user interaction with a system prompt asking for permission. This issue was fixed in commit 0c75fb57f89d0b7d9b180026bc2624b7dcf807da

Summary		(es) La configuración de Phoenix Code en macOS, en concreto la presencia de los permisos "com.apple.security.cs.allow-dyld-environment-variables" y "com.apple.security.cs.disable-library-validation", permite la inyección de librerías dinámicas (Dylib). Un atacante local con acceso sin privilegios puede usar variables de entorno como DYLD_INSERT_LIBRARIES para inyectar código correctamente en el contexto de la aplicación y eludir la Transparencia, Consentimiento y Control (TCC). El acceso a recursos adquiridos se limita a los permisos previamente otorgados por el usuario. El acceso a otros recursos, además de los permisos otorgados, requiere la interacción del usuario con un mensaje del sistema solicitando permiso. Este problema se solucionó en el commit 0c75fb57f89d0b7d9b180026bc2624b7dcf807da.
