GHSA-QHWX-74W5-XHXQ vm2: NodeVM builtin allowlist bypass via node:test.run() execArgv allows sandbox escape

Summary On Node.js 24 and newer, vm2 can expose the host node:test module to sandboxed NodeVM code when the embedder explicitly allows the node:test builtin. Sandbox code can reach that module through require'node:node:test' and call run with attacker-controlled execArgv. node:test.run starts a...

vm2 CLI provides no sandbox isolation - host-realm require() is reachable from sandboxed scripts

Summary The vm2 command-line tool installed by npm install -g vm2 and documented in the README's "CLI" section runs the supplied script under NodeVM with require:external:true and no root / context / builtin configured. With these defaults the resolver loads every relative or absolute require...

GHSA-8686-VHFX-7R3J vm2: NodeVM node:-prefixed negative builtin deny bypass exposes child_process

Summary NodeVM normalizes node:-prefixed builtin specifiers during require resolution, but it does not normalize user-provided negative builtin entries in wildcard policy. As a result, this configuration: js new NodeVM require: builtin: '', '-node:childprocess' ; does not deny the canonical...

vm2: GHSA-m283-3h24-438v fix bypass leads to host RCE via call/apply indirection

Summary Untrusted JavaScript run by vm2 can escape the sandbox and execute arbitrary commands in the host Node.js process when an embedder-exposed host Promise rejects. This is an incomplete fix for GHSA-m283-3h24-438v: the advisory's capability-bearing rejection rebuild runs only through this...

vm2 NodeVM can replace the host process TLS trust store

Summary vm2 3.11.6 exposes the host tls module to a NodeVM when that builtin is explicitly allowed. Although the module object is wrapped as read-only, its functions still execute against process-wide host state. On Node.js versions that provide tls.setDefaultCACertificates, sandbox code can...

CVE-2026-103754

A flaw in ansible-runner 's unstream_dir() function allows for path traversal and symlink escape during the extraction of a streamed zip archive. The vulnerability exists because the function fails to validate symbolic link targets and applies chmod() and utime() to unsanitized filesystem paths d...

A flaw was found in ansible-runner. The unstreamdir function, which receives and extracts a streamed zip archive on the worker side of the ansible-runner transmit/worker protocol, re-creates symbolic links from archive content without validating the link target and applies chmod and utime to an...
