CVE-2026-47698
Last modified
CVE-2026-47698 is a critical-severity vulnerability rated 9.8/10 on the CVSS scale. vm2 is an open source vm/sandbox for Node.js. Prior to 3.11.6, lib/bridge.js and lib/setup-sandbox.js fail to block stacked indirection through Function.prototype.call around dangerous host prototype getter and setter mutators, allowing sandbox code to sever a host intrinsic's prototype chain and reach e.constructor.constructor for arbitrary host command execution. EPSS estimates a 0.56% chance of exploitation in the next 30 days.
