imgdecode@1.0.3
Native image buffer decoder for Node.js build pipelines
AI Security Review
scanned 11d ago · by lpm-firewall-aiThe entrypoint activates a native initializer that fetches remote data and routes non-image responses into process injection code. This concrete remote execution behavior warrants blocking publication.
Static reason
No blocking static signals were detected.
Trigger
Importing the package on Windows when the native addon's console check succeeds.
Impact
A remote payload can execute inside another process.
Mechanism
The addon fetches and reads remote bytes; responses that fail its image signature checks are passed to a helper using process creation and remote memory APIs.
Attack narrative
Importing the package loads its Windows native addon. During initialization, the addon fetches remote content and passes responses that do not match its image checks to process execution helpers. This is an active remote payload execution path.
AI rationale
The entrypoint activates a native initializer that fetches remote data and routes non-image responses into process injection code. This concrete remote execution behavior warrants blocking publication.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- The package entrypoint immediately loads the bundled Windows native addon when imported.
- The native initializer calls a routine that opens a WinINet URL and reads the response.
- Downloaded content is checked for image signatures; other content reaches a helper that processes the supplied bytes.
- The helper contains obfuscated process API names, including process creation, remote memory allocation, and thread resumption, and makes indirect calls using supplied data.
