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. LPM treats this as warn-only first-party agent extension lifecycle risk. Installing the package mutates the consuming project's Cursor configuration, package.json, .gitignore, and an existing Husky hook. It installs local commit-review automation that can block commits. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 90.0% - **Started:** 2026-08-27T18:54:18.504Z - **Finished:** 2026-08-27T18:55:04.725Z - **Download time:** 502 ms - **Static scan time:** 36 ms - **AI review time:** 45683 ms - **Total time:** 46221 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:** Installing the package mutates the consuming project's Cursor configuration, package.json, .gitignore, and an existing Husky hook. It installs local commit-review automation that can block commits. - **Trigger:** npm install runs postinstall; later git commit triggers the installed hooks. - **Impact:** The package gains recurring local execution during commits and can prevent commits based on its review rules. - **Evidence paths:** package.json, scripts/install.js, .cursor/hooks.json, .cursor/hooks/on-git-commit-review.py, .cursor/hooks/rules-review.py - **Review source:** ai\_review - **Reviewed:** 2026-08-27T18:55:04.725Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic project configuration and commit-hook installation. - **Rationale:** This is a disclosed, package-aligned Cursor extension with local-only review logic, not confirmed malware. Its postinstall mutation of project configuration and commit hooks is a real lifecycle risk that warrants a warning. - **Files touched:** .cursor, package.json, .gitignore, .husky/pre-commit, .cursor/reviews/project.auto.md ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The postinstall hook runs the installer automatically., The installer force-copies its .cursor directory into the consuming project and rewrites package metadata., When Husky exists, installation adds a pre-commit command that runs the package's review script., The installed Cursor hook intercepts git commit commands and can deny them. - **Evidence against:** No network, credential collection, shell download, or remote payload execution was found., The review script only scans project files and writes a local review report., The behavior matches the package's stated Cursor rules and review functionality. ## Affected versions and remediation This report applies to cursor-package-funtech@1.0.4. - Review the evidence and your use of cursor-package-funtech@1.0.4 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.
