OpenSSF/OSV Malicious Advisory
imported 4d ago · by OpenSSF/OSVOpenSSF/OSV advisory MAL-2026-6359 confirms this npm version as malicious.
Independent LPM AI assessment
CleanIndependent AI assessment: clean. LPM AI assessed this version as clean; the assessments disagree.
Source inspection found a narrowly scoped dependency patch and user-invoked output uploads directed through environment-configured R2 settings. Screenshot requests are opt-in and require a SnapAPI key, so the scanner signals do not establish malicious behavior.
Independent scan evidence
public snapshot- The manifest points to index.js and defines a postinstall hook that runs a local patch script.
- The patch script copies the package’s vendored asset extractor over the installed fetch-page-assets entry only when both files exist.
- Preview generation is opt-in and requires a configured SnapAPI key; the default endpoint is the SnapAPI screenshot service.
- Generated output uploads use an R2 client configured from environment settings and send files to that configured bucket.
- The postinstall hook changes an installed dependency in place, but the inspected source limits that change to the package’s vendored fetch-page-assets replacement.
