q-koa@13.8.19
AI Security Review
scanned 27d ago · by lpm-firewall-aiThe inspected source contains a request-driven eval-to-VM execution path, creating a critical remote-code-execution risk. No evidence indicates that this package performs a covert package-level attack.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
A request reaches a supported generic model operation with an include or relate body value.
Impact
An attacker able to reach the operation under its authentication and routing configuration may execute arbitrary JavaScript in the VM context and potentially compromise the application.
Mechanism
Request-body strings are wrapped in eval syntax and passed to nodeVm.runInNewContext before being invoked with application state.
AI rationale
The inspected source contains a request-driven eval-to-VM execution path, creating a critical remote-code-execution risk. No evidence indicates that this package performs a covert package-level attack.
Evidence
core/app.js
Decision evidence
public snapshotAI called this Suspicious at 93.0% confidence as Critical Vulnerability with low false-positive risk.
Evidence for warning
- The manifest exposes a normal JavaScript entrypoint and contains no automatic install lifecycle hook.
- The server formats the request-controlled include and relate values as eval expressions and runs them in a new VM context.
- The values are read from the HTTP request body in the generic model operation path.
- Authentication is attempted using a token from a request header, cookie, or query parameter, but this does not validate the code-bearing values.
Evidence against
- No package-install hook, external endpoint, credential collection, or persistence behavior was identified in the inspected entrypoint and vulnerable path.
