Node.js permission model bypass!

  • Permissions:
    • --allow-fs-read=/sandbox
    • --allow-fs-write=/sandbox
  • Hardening:
    • --jitless
    • --freeze-flags-after-init
    • --frozen-intrinsics
    • Remove access to node:sqlite, node:ffi, and internal modules
  • Goal:
    • RCE

Note: Although unintended, this challenge may be solvable using a binary exploitation approach. However, the intended solution does not rely on any memory-safety bugs.
