Summary

Duplicate Advisory: vm2: NodeVM node:-prefixed negative builtin deny bypass exposes child_process

Details

Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-8686-vhfx-7r3j. This link is maintained to preserve external references.

Original Description

vm2 through 3.11.6 does not normalize node:-prefixed builtin specifiers when evaluating user-supplied negative (deny) entries in a NodeVM wildcard require policy. Although NodeVM strips the node: prefix during require() resolution, negative wildcard entries are matched by exact string comparison against the canonical builtin names, so a policy such as new NodeVM({ require: { builtin: ['*', '-node:child_process'] } }) fails to deny the canonical child_process module. Sandboxed code can therefore obtain the host child_process builtin via require('child_process') or require('node:child_process'), gaining references to process-spawning APIs such as execSync and spawn, which is equivalent to host command-execution capability for untrusted sandbox code. Fixed in vm2 3.11.7. (Suggested title: "vm2 before 3.11.7: NodeVM builtin deny-list bypass via node:-prefixed specifiers exposes child_process")
