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. When the userscript runs on hdoujin.org, it obtains an image base URL from api.hdoujin.org and forwards the page cookie to that returned base. The unrestricted cross-origin grant leaves the receiver insufficiently constrained. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 84.0% - **Started:** 2026-09-04T01:16:01.960Z - **Finished:** 2026-09-04T01:18:06.229Z - **Download time:** 765 ms - **Static scan time:** 17071 ms - **AI review time:** 106431 ms - **Total time:** 124269 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:** When the userscript runs on hdoujin.org, it obtains an image base URL from api.hdoujin.org and forwards the page cookie to that returned base. The unrestricted cross-origin grant leaves the receiver insufficiently constrained. - **Trigger:** A user installs the userscript and opens a supported hdoujin.org gallery. - **Impact:** A compromised or malicious API response could receive the user's hdoujin.org session cookie. - **Evidence paths:** ComicRead-AdGuard.user.js - **Review source:** ai\_review - **Reviewed:** 2026-09-04T01:18:06.229Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Cookie forwarding to an API-selected cross-origin image host. - **Rationale:** The package has no install-time hooks or local-system behavior, but its userscript can forward a site cookie to a remotely selected cross-origin destination. That is an unresolved credential-exposure risk requiring a warning. - **Files touched:** ComicRead-AdGuard.user.js - **Network endpoints:** api.hdoujin.org ### Review decision - **Verdict:** Suspicious - **Confidence:** 84.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The userscript requests unrestricted cross-origin access and GM\_xmlhttpRequest., On hdoujin.org, it sends document.cookie to a base URL supplied by a remote API response., The package contains a browser userscript payload rather than only a library entrypoint. - **Evidence against:** package.json has no preinstall, install, or postinstall hook., The source structure and metadata describe comic-reader features, and the observed cookie use is within a site-specific image-loading path., No local file harvesting, shell execution, persistence, or npm lifecycle mutation was found. ## Affected versions and remediation This report applies to @hymbz/comic-read-script@12.11.0. - Review the evidence and your use of @hymbz/comic-read-script@12.11.0 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.
