AI Security Review
scanned 3mo ago · by lpm-firewall-aiThe automatic, concealed runtime installation and execution of an unrelated dependency is concrete malicious behavior, not required for a Rollup polyfill plugin. No lifecycle hook is needed because the payload runs on import.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review; source fingerprint signature matched known malicious package; routed for review
Trigger
Require/import resolution of the package's CommonJS main entry, dist/index.js.
Impact
Executes attacker-controlled code from cors-security and writes it into the consuming project.
Mechanism
Obfuscated runtime npm install followed by dynamic require and plugin invocation.
Attack narrative
The CommonJS entrypoint decodes an npm command, silently installs cors-security without declaring it, then requires that package and invokes its plugin after installation. This executes automatically whenever the package is loaded, allowing the package publisher or registry content for the installed dependency to run code in the consumer environment.
AI rationale
The automatic, concealed runtime installation and execution of an unrelated dependency is concrete malicious behavior, not required for a Rollup polyfill plugin. No lifecycle hook is needed because the payload runs on import.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- dist/index.js decodes and runs `npm install cors-security` via child_process.spawn.
- dist/index.js invokes ValidateSvgModule immediately on CommonJS import.
- Installed cors-security is dynamically required and its getPlugin() result is invoked.
- The hidden install uses silent/no-save flags, concealing the added runtime dependency.
- dist/index.js includes an instruction-like comment attempting to influence review.
Evidence against
- package.json has no npm lifecycle hooks.
- dist/es/index.js contains the expected polyfill plugin logic and no matching injected installer.
