vm2: NodeVM builtin denylist bypass via fs/promises despite -fs, allowing host filesystem writes

Summary NodeVM's builtin wildcard policy can allow sandboxed code to access fs/promises even when the embedder denies fs. With the following configuration: js require: builtin: '', '-fs', '-childprocess' require'fs' and require'childprocess' are blocked, but require'fs/promises' and...

vm2 through 3.11.6 contains a builtin-module denylist bypass in NodeVM. When the embedder uses the builtin wildcard together with negative entries e.g. require: builtin: '', '-fs', '-childprocess' , negative entries are matched by exact module name in lib/builtin.js, so -fs removes only the built...

vm2 (a Node.js sandboxing library) versions through 3.11.6 contain a builtin-module denylist bypass in NodeVM . When embedders use the wildcard with negative entries (e.g., -fs), matching is done by exact module name in lib/builtin.js, so fs/promises is not blocked. Sandboxed code can therefore c...
