CVE-2026-32046

// PoC Concept: Demonstrating the lack of sandbox protection. // This snippet simulates a renderer process executing a system command, // which would normally be blocked by the OS-level sandbox. #include <stdio.h> #include <stdlib.h> // Simulated renderer exploit function void simulate_renderer_exploit() { printf("[+] Renderer process compromised...\n"); // Check if sandbox is active (pseudo-code logic) // In a vulnerable build, this check returns false bool is_sandbox_active = false; if (!is_sandbox_active) { printf("[!] Sandbox is DISABLED. Executing code on host OS...\n"); // Arbitrary code execution on the host system system("calc.exe"); // Example: Launch calculator to prove execution printf("[+] Code executed successfully on host.\n"); } else { printf("[-] Sandbox is active. Exploit blocked.\n"); } } int main() { simulate_renderer_exploit(); return 0; }
