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 user-invoked launcher fetches an executable archive chosen by a registry response and executes it without signature or checksum verification. Its install hook also removes named binaries in the user configuration directory. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-09-12T11:20:18.513Z - **Finished:** 2026-09-12T11:21:05.742Z - **Download time:** 509 ms - **Static scan time:** 143 ms - **AI review time:** 46577 ms - **Total time:** 47229 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 user-invoked launcher fetches an executable archive chosen by a registry response and executes it without signature or checksum verification. Its install hook also removes named binaries in the user configuration directory. - **Trigger:** Running any package bin command; the binary removal occurs during npm postinstall. - **Impact:** A compromised registry or release source can supply code that runs as the invoking user; installation can remove an existing codebuff binary. - **Evidence paths:** index.js, postinstall.js - **Review source:** ai\_review - **Reviewed:** 2026-09-12T11:21:05.742Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Unverified remote binary download and execution, plus install-time binary deletion. - **Rationale:** The package contains a concrete unverified remote-code execution path and an install-time deletion of a potentially foreign binary. Static source does not establish credential theft, stealth persistence, or an automatically executed remote payload at install time. - **Files touched:** ~/.config/manicode/codebuff, ~/.config/manicode/codebuff-mod, ~/.config/manicode/.download-temp, ~/.config/manicode/codebuff-metadata.json, ~/.config/manicode/tree-sitter.wasm - **Network endpoints:** registry.npmjs.org, github.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The launcher selects the latest registry version, downloads a GitHub release archive, and executes its extracted binary without an integrity check., Installation deletes both the fork binary and a separately named existing codebuff binary from the user configuration directory., The downloaded executable is given execute permission and launched with the caller’s arguments. - **Evidence against:** The install hook only removes named local binaries and does not download or execute a payload., No source evidence shows credential harvesting, project-file writes, or secret exfiltration., Network destinations in the launcher are the npm registry and the declared GitHub release repository. ## Affected versions and remediation This report applies to codebuff-mod@1.6.0. - Review the evidence and your use of codebuff-mod@1.6.0 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.
