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 userscript has a remote code execution exposure in its Hitomi integration. No npm install-time attack surface was identified. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-09-28T02:37:02.108Z - **Finished:** 2026-09-28T02:37:53.977Z - **Download time:** 1019 ms - **Static scan time:** 5612 ms - **AI review time:** 45237 ms - **Total time:** 51869 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:** The userscript has a remote code execution exposure in its Hitomi integration. No npm install-time attack surface was identified. - **Trigger:** A user visits a matching comic site and invokes the affected image-list functionality. - **Impact:** A compromised or malicious response from that host could execute code in the userscript context. - **Evidence paths:** ComicRead-AdGuard.user.js - **Review source:** ai\_review - **Reviewed:** 2026-09-28T02:37:53.977Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The script requests a remote gg.js response and evaluates the returned text without integrity validation. - **Rationale:** The direct network-to-eval path is a concrete remote-code execution risk. It warrants a warning, but there is no evidence of malicious installation behavior or a confirmed payload. - **Network endpoints:** https://ltn.${domain}/gg.js ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The manifest contains ordinary development scripts and no npm lifecycle hook., The userscript downloads JavaScript from a dynamically selected host and passes the response directly to eval., This occurs while assembling a comic image list, so a changed remote response can execute when that site feature is used. - **Evidence against:** No install-time package mutation was identified., The reviewed remote-code path is tied to a comic-site integration rather than a demonstrated unrelated payload recipient. ## Affected versions and remediation This report applies to @hymbz/comic-read-script@12.15.0. - Review the evidence and your use of @hymbz/comic-read-script@12.15.0 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.
