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. On supported comic pages, the userscript fetches server-controlled text and passes it to eval. Its wildcard page and network permissions make a compromised site capable of executing code in the userscript context. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-09-01T18:59:58.400Z - **Finished:** 2026-09-01T19:01:25.550Z - **Download time:** 505 ms - **Static scan time:** 18981 ms - **AI review time:** 67663 ms - **Total time:** 87150 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:** On supported comic pages, the userscript fetches server-controlled text and passes it to eval. Its wildcard page and network permissions make a compromised site capable of executing code in the userscript context. - **Trigger:** A user installs the userscript and opens an affected comic page that returns a crafted response. - **Impact:** A compromised supported site can run arbitrary JavaScript with the userscript's granted access. - **Evidence paths:** ComicRead.user.js - **Review source:** ai\_review - **Reviewed:** 2026-09-01T19:01:25.550Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote response text is evaluated in a privileged userscript. - **Rationale:** No install-time malware or package-owned credential collector was found, but direct evaluation of server responses under broad userscript permissions is a concrete remote-code-execution risk. This warrants a warning rather than a malicious verdict because the inspected code does not show a separate attacker-controlled payload or exfiltration endpoint. - **Files touched:** ComicRead.user.js - **Network endpoints:** chapterfun.ashx ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Critical Vulnerability - **False-positive risk:** Low - **Evidence for warning:** The userscript evaluates text returned by comic-site HTTP endpoints., It requests broad page and cross-origin access, increasing the impact of a compromised supported site. - **Evidence against:** package.json has no preinstall, install, or postinstall hook., The inspected token use sends it to the listed comic API endpoints rather than a package-owned collector. ## Affected versions and remediation This report applies to @hymbz/comic-read-script@12.10.0. - Review the evidence and your use of @hymbz/comic-read-script@12.10.0 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.
