Its behavior remains unresolved; no confirmed attack was established. - **Trigger:** Importing imgdecode, with native loading dependent on platform compatibility. - **Impact:** Unexplained native execution presents unresolved risk, but malicious effects were not demonstrated. - **Evidence paths:** index.js, prebuilds/win32-x64/imgdecode.node, package.json - **Review source:** ai\_review - **Reviewed:** 2026-10-22T20:35:07.883Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The entrypoint loads imgbundle and attempts native addon initialization while exporting a function that returns null. - **Rationale:** Automatic native loading, networking and decryption imports, and a nonfunctional public decoder warrant a warning pending clarification of the native behavior. The manifest mismatch hint and binary markers do not establish a concrete malicious chain. ### Review decision - **Verdict:** Suspicious - **Confidence:** 72.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** High - **Evidence for AI warning decision:** index.js automatically loads imgbundle and attempts to load a Windows native addon on import., The native addon contains Internet URL access and cryptographic decryption import markers., The exported load function returns null, leaving the native addon's purpose unexplained., package.json declares imgbundle as a runtime dependency and contains no lifecycle scripts. - **Evidence against:** No concrete endpoint, credential harvesting, malicious write, or payload execution chain was established., Native networking and cryptography imports alone do not prove malicious behavior. ## Affected versions and remediation This report applies to imgdecode@1.0.1. - Avoid installing imgdecode@1.0.1. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
