Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Blocked & quarantined** — The relay operator can receive and potentially use the user's GitHub credential. This contradicts the README's claim that the PAT only goes to GitHub. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Matched malicious - **Public report status:** Published - **Threat category:** Credential Exfiltration - **Selected version:** 0.25.7 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The component silently sends a stored GitHub credential to the screen-time relay, which defaults to authBase, despite the README promising the PAT only goes to GitHub. The Trojan Source alert on comment-format.js was not confirmed as attack behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 95.0% - **Started:** 2026-11-01T17:01:36.049Z - **Finished:** 2026-11-01T17:02:27.937Z - **Download time:** 760 ms - **Static scan time:** 266 ms - **AI review time:** 50861 ms - **Total time:** 51888 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 React review component forwards the stored GitHub token to the configured screen-time relay. - **Trigger:** Automatic during active review-time reporting and after a successful issue filing when a relay is configured and a token is stored. - **Impact:** The relay operator can receive and potentially use the user's GitHub credential. This contradicts the README's claim that the PAT only goes to GitHub. - **Evidence paths:** dist/react/github-issue-review.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-11-01T17:02:27.937Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The relay defaults to authBase; report requests POST to its /screentime path with the GitHub token in a Bearer authorization header. - **Attack narrative:** When a relay is configured, the React component defaults its screen-time destination to authBase and automatically posts review reports there with the stored GitHub token as a Bearer credential. This occurs during active review-time reporting and after an issue is filed. The README says the PAT only leaves the browser on direct requests to GitHub, so users are not told that this credential is forwarded to the relay. - **Rationale:** The component silently sends a stored GitHub credential to the screen-time relay, which defaults to authBase, despite the README promising the PAT only goes to GitHub. The Trojan Source alert on comment-format.js was not confirmed as attack behavior. - **Files touched:** dist/react/github-issue-review.js, localStorage key slowcook.review-overlay.reviewer-token.{owner}/{repo} - **Network endpoints:** https://api.github.com, ${screentimeBase}/screentime (screentimeBase defaults to authBase) ### Review decision - **Verdict:** Malicious - **Confidence:** 95.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The screen-time relay defaults to the configured authBase., The relay receives the stored GitHub token in a Bearer header on a POST to /screentime., The component sends relay reports automatically during active review time and after successful issue filing., The README says the PAT only leaves the browser on direct fetches to GitHub's API. - **Evidence against:** The package is designed to file review comments as GitHub issues, and its GitHub API requests send tokens to api.github.com., The relay host is configurable rather than a hard-coded collector., The package declares no install lifecycle scripts. ## Affected versions and remediation This report applies to @slowcook-ai/review-overlay@0.25.7. - Avoid installing @slowcook-ai/review-overlay@0.25.7. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
