0 CVE-2026-25881 is a critical prototype pollution vulnerability in SandboxJS versions prior to 0.8.31. It allows sandboxed JavaScript code to escape isolation by mutating host built-in prototypes such as Map.prototype or Set.prototype. This occurs because the isGlobal protection flag is improperly stripped when global prototype references are passed through array literals, enabling persistent prototype pollution. Exploiting this flaw can lead to remote code execution (RCE) if polluted properties are used in sensitive operations like execSync. The vulnerability has a CVSS score of 9.1, indicating high severity, and affects applications relying on SandboxJS for secure code execution.
