Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1. High: Osv Malicious Advisory - **Category:** External Intel - **Confidence:** 100.0% Package name \`pdf-lib-enhanced\` mimics the widely-used \`pdf-lib\` library and ships a verbatim copy of upstream's README. \`package.json\` declares \`repository.url\` pointing at a fresh GitHub account (\`harunosakura030303-maker/pdf-lib-enhanced\`) while \`bugs.url\` still points at the original \`Hopding/pdf-lib\` project — a metadata mismatch consistent with a hastily-forked squat. The \`dist/\` directory contains unrelated SheetJS assets (\`xlsx.full.min.js\`, \`xlsx.zahl.js\`, \`cpexcel.js\`, etc.) that have no purpose in a PDF library. However, the CommonJS main entry (\`cjs/index.js\`) re-exports the upstream pdf-lib API without any credential reads, exfiltration, dropper, or silent-relay behavior, and \`package.json\` declares no \`preinstall\`/\`install\`/\`postinstall\`/\`prepare\` lifecycle scripts, so installing the package does not auto-execute any code. The dormant SheetJS bundles are not referenced from the main entry. Name-similarity to a top-tier package combined with an irrelevant payload bundle warrants human assessment of intent, but there is no concrete installer-harm mechanism observable in the shipped code. \#\# Source: ghsa-malware (a4da0334724e86909030ba354dab57e4c522c139a925d3ec06559541179c562e) Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it. ## Dependencies and install lifecycle - **Lifecycle scripts present:** No - **Dependencies:** 0 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 0 - **Published dependency-graph edges:** 0 ## Package metadata - **Package:** pdf-lib-enhanced - **Ecosystem:** npm - **Version:** 2.2.0 - **Version published:** 2026-05-25T13:37:08.530Z - **Package first seen:** 2026-07-08T20:00:19.281Z - **Package last seen:** 2026-07-08T20:00:19.281Z - **Known versions:** 1 - **Latest version:** 2.2.0 - **Appeal under review:** No ## References - [HTML security report]() - [OpenSSF/OSV advisory]() - [ADVISORY]() - [PACKAGE]()
