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. A supported-site adapter evaluates JavaScript downloaded at runtime. That response runs in a userscript granted unrestricted cross-origin request access. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 89.0% - **Started:** 2026-09-13T08:14:56.801Z - **Finished:** 2026-09-13T08:16:09.712Z - **Download time:** 778 ms - **Static scan time:** 5026 ms - **AI review time:** 67106 ms - **Total time:** 72911 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:** A supported-site adapter evaluates JavaScript downloaded at runtime. That response runs in a userscript granted unrestricted cross-origin request access. - **Trigger:** A user visits a supported Hitomi gallery and the adapter loads its image list. - **Impact:** A compromised or malicious remote host could execute code in the userscript context and use its granted APIs. - **Evidence paths:** ComicRead-AdGuard.user.js - **Review source:** ai\_review - **Reviewed:** 2026-09-13T08:16:09.712Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote response evaluated with eval in a privileged userscript. - **Rationale:** The package is not confirmed malicious, but direct evaluation of a remote script combined with broad userscript permissions is an unresolved high-impact vulnerability. The scanner's alleged default credential exfiltration was not confirmed by source inspection. - **Files touched:** ComicRead-AdGuard.user.js - **Network endpoints:** ltn.gold-usergeneratedcontent.net ### Review decision - **Verdict:** Suspicious - **Confidence:** 89.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Critical Vulnerability - **False-positive risk:** Medium - **Evidence for warning:** The Hitomi adapter fetches a remote JavaScript response and directly evaluates it., The userscript requests unrestricted cross-origin access and privileged GM APIs, increasing the impact of that remote execution. - **Evidence against:** package.json contains no preinstall, install, or postinstall lifecycle hook., The reported translation upload is disabled by default and sends the selected image plus translation settings to its stated service., No package-controlled credential collection or covert exfiltration path was confirmed. ## Affected versions and remediation This report applies to @hymbz/comic-read-script@12.13.0. - Review the evidence and your use of @hymbz/comic-read-script@12.13.0 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.
