vm2 Custom Module Resolver Can Bypass the External Package Allowlist by Loading a Colliding Host Package

Summary vm2 is a sandbox library for isolating and executing untrusted JavaScript code inside a Node.js process. It can restrict access to built-in modules and external packages. When NodeVM enables an external allowlist together with a custom resolve callback, vm2 checks the requested package na...

GHSA-6RH5-QQ4Q-97XH 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...

GHSA-633R-HQ9M-C4FF vm2: vm.freeze()/vm.readonly() bypass via accessor descriptor

Summary Untrusted JavaScript running inside new VM.run / new NodeVM.run can bypass vm.freeze / vm.readonly and mutate a host object the embedder explicitly marked read-only - the documented contract is "prevent sandboxed scripts from adding, changing, or deleting properties". If the frozen host...

vm2: NodeVM nesting guard accepts array-shaped require and permits host RCE

Summary The NodeVM constructor computes hasRealRequireConfig using typeof requireOpts === 'object' && requireOpts !== null, so require: bypasses the guard intended to reject nesting without an explicit require configuration. makeResolverFromLegacyOptions then destructures the array to undefined...

GHSA-647F-G98J-QQ25 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 crypto builtin loads attacker native code through setEngine

Summary vm2 3.11.6 exposes the host crypto module to a NodeVM when that single builtin is allowed. The module is presented through a read-only bridge, but its functions still execute with host-process authority. crypto.setEngine accepts a filesystem path and asks OpenSSL to dynamically load the...

fast-uri: fast-uri: Host confusion via skipped IDN canonicalization

A flaw was found in fast-uri, a URI parser for Node.js. This vulnerability arises because the parser fails to consistently convert internationalized domain names IDN to their standard ASCII form when processing scheme-relative references. This inconsistency can lead to host confusion, where an...

foreman: Excessive Permissions for Viewer Role on Preview

A flaw was found in Foreman. This vulnerability allows an authenticated user with low-level Viewer permissions to cause unauthorized information disclosure by submitting requests to template preview endpoints. By exploiting this issue, the user can access sensitive data, such as host root...

fast-uri: fast-uri: Host confusion via unbalanced URI brackets can bypass security policies

A flaw was found in fast-uri. The library incorrectly processes Uniform Resource Identifier URI hosts containing unbalanced brackets, leading to a discrepancy in how the host is parsed by fast-uri compared to other HTTP clients. This host confusion can allow an attacker to bypass security policie...
