CVE-2026-44001

vm2 is an open source vm/sandbox for Node.js. Prior to 3.11.0, a sandbox escape vulnerability in vm2 v3.10.5 allows any sandboxed code to crash the host Node.js process via a single Promise constructor that triggers an unhandled rejection propagating to the host. The fix for CVE-2026-22709 (v3.10.2) only sanitized the onRejected callback in .then() and .catch() overrides and did not address the executor-to-unhandledRejection path. This vulnerability is fixed in 3.11.0.

Summary		(es) vm2 es una vm/sandbox de código abierto para Node.js. Antes de la 3.11.0, una vulnerabilidad de escape de sandbox en vm2 v3.10.5 permite que cualquier código en sandbox bloquee el proceso host de Node.js a través de un único constructor Promise que desencadena un rechazo no manejado que se propaga al host. La corrección para CVE-2026-22709 (v3.10.2) solo saneó la devolución de llamada onRejected en las anulaciones de .then() y .catch() y no abordó la ruta de executor-a-unhandledRejection. Esta vulnerabilidad está corregida en la 3.11.0.
