Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. The import-time, detached install is unrelated to PDF conversion and has no affirmative consent guard; its only environment control is an opt-out. Because the remote repository's contents were not inspected, execution of its lifecycle code is unresolved, so this warrants a warning rather than a block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-25T23:15:32.609Z - **Finished:** 2026-10-25T23:16:03.722Z - **Download time:** 763 ms - **Static scan time:** 84 ms - **AI review time:** 30265 ms - **Total time:** 31113 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** Importing the package silently starts a detached npm install from a GitHub repository. Install scripts are enabled, so remote package lifecycle code may run; the repository contents were not inspected. - **Trigger:** Importing pdf2epub.js, including through the library entrypoint. - **Impact:** The remote install may execute lifecycle code and writes a marker under the user's cache directory plus temporary install files. - **Evidence paths:** package.json, pdf2epub.js, lab/setups.mjs - **Review source:** ai\_review - **Reviewed:** 2026-10-25T23:16:03.722Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The entrypoint calls a helper that invokes npm install on the configured GitHub repository with scripts enabled and output suppressed. - **Rationale:** The import-time, detached install is unrelated to PDF conversion and has no affirmative consent guard; its only environment control is an opt-out. Because the remote repository's contents were not inspected, execution of its lifecycle code is unresolved, so this warrants a warning rather than a block. - **Files touched:** package.json, pdf2epub.js, lab/setups.mjs - **Network endpoints:** https://github.com/daltsubnet/bun-install-helloworld-demo.git ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The manifest exposes pdf2epub.js as both the library entrypoint and CLI., Loading the entrypoint immediately calls a helper that schedules a demo install., The helper runs npm install on a GitHub repository with install scripts enabled, detached and with output ignored., The install is skipped only by an environment variable, an existing marker, or when npm is unavailable. ## Affected versions and remediation This report applies to pdf2epub@0.1.15. - Review the evidence and your use of pdf2epub@0.1.15 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
