Vulnerability Type: Unpinned dependency installation and unsafe host-runtime integration
Risk Level: Mediumpowershell npm install --ignore-scriptspowershell npm install js-tiktoken --ignore-scriptsTechnical Analysis
The installation guide directs users to install
js-tiktokenwithout specifying an exact version and provides no lockfile or integrity verification mechanism. Consequently, the package version and transitive dependency graph are resolved from the package registry at installation time and may differ between installations.The instructions subsequently place the dependency in the Gateway's
node_modulesenvironment. Although--ignore-scriptsprevents package lifecycle scripts from executing during installation, it does not prevent JavaScript contained in the dependency from executing later when the Gateway or plugin imports it. A compromised package release, compromised maintainer account, registry substitution, or malicious transitive dependency could therefore introduce executable code into the trusted Gateway process.Attack Path
- An attacker compromises the
js-tiktokenpackage, one of its transitive dependencies, or the package publication account. - The attacker publishes a malicious version that satisfies the unconstrained installation request.
- An administrator follows the guide and runs
npm install js-tiktoken --ignore-scripts. - npm resolves and installs the attacker-controlled version because no exact version, lockfile, or integrity allowlist is enforced.
- The dependency is made available in the Gateway runtime.
- When the memory plugin imports the dependency, its runtime module code executes inside the Gateway process despite lifecycle scripts having been disabled.

Remediation Suggestions
- Pin
js-tiktokenand every direct dependency to an explicitly reviewed version rather than using an unconstrained package name. - Distribute a reviewed
package-lock.jsoncontaining npm integrity hashes and require reproducible installation withnpm ci --ignore-scripts. - Verify dependency provenance, publisher identity, signatures or attestations, and integrity metadata before installation.
- Review and audit the complete transitive dependency graph; use automated vulnerability and package-reputation scanning in the release process.
- Avoid manually copying packages into the Gateway's shared
node_modules. Package the plugin with an isolated, reviewed dependency tree or use an officially supported dependency-loading mechanism. - Run the Gateway under a dedicated, least-privileged operating-system account and restrict its access to credentials, configuration, and unrelated user files.
- Pin approved package versions in organizational policy and use a trusted internal registry or immutable artifact repository where practical.
- Retain
--ignore-scriptsas defense in depth, but do not treat it as protection against malicious runtime module code.
