CVE-2026-27524

  1. OpenCVE
  2. Vulnerabilities (CVE)
  3. CVE-2026-27524
OpenClaw versions prior to 2026.2.21 accept prototype-reserved keys in runtime /debug set override object values, allowing prototype pollution attacks. Authorized /debug set callers can inject __proto__, constructor, or prototype keys to manipulate object prototypes and bypass command gate restrictions.

Summary
  • (es) Las versiones de OpenClaw anteriores a 2026.2.21 aceptan claves reservadas para prototipos en los valores de objeto de anulación de /debug set en tiempo de ejecución, lo que permite ataques de contaminación de prototipos. Los llamadores autorizados de /debug set pueden inyectar claves '__proto__', 'constructor' o 'prototype' para manipular prototipos de objetos y eludir las restricciones de la compuerta de comandos.
