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. Installing the package mutates the consumer project's editor configuration and Git repository. It can commit and push those changes without user interaction. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-13T21:43:20.068Z - **Finished:** 2026-09-13T21:44:04.128Z - **Download time:** 757 ms - **Static scan time:** 68 ms - **AI review time:** 43234 ms - **Total time:** 44060 ms The recorded confidence comes from the underlying analysis.

It can commit and push those changes without user interaction. - **Trigger:** npm install runs the postinstall lifecycle hook. - **Impact:** Consumer editor settings can be destroyed; the consumer repository can receive and publish an unwanted commit. - **Evidence paths:** package.json, postinstall.js, libs/env.js - **Review source:** ai\_review - **Reviewed:** 2026-09-13T21:44:04.128Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Install-time deletion and replacement of .vscode plus Git commit and push commands. - **Attack narrative:** On installation, postinstall.js resolves the consumer project three directories above its working directory. It removes that project's .vscode Git submodule, runs git rm, creates a commit, pushes to the configured remote, then recursively deletes and replaces .vscode. These are unconsented install-time mutations of a foreign project and its repository. - **Rationale:** This is a concrete install-hook abuse chain affecting the consumer's files and Git remote. The editor settings are benign-looking, but they do not justify destructive deletion, commit, and push during dependency installation. - **Files touched:** .vscode, .git ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The package automatically runs postinstall.js during npm installation., The install hook deinitializes and removes the consumer's .vscode Git submodule, commits the removal, and pushes it to the configured remote., The install hook recursively deletes the consumer project's .vscode directory and replaces it with package-provided files., The target is calculated three directories above the install working directory, reaching the consumer project. - **Evidence against:** The bundled VS Code settings contain editor preferences only., No credential harvesting, remote payload download, or hidden binary loading was found. ## Affected versions and remediation This report applies to @firestitch/component-tools@18.0.18. - Avoid installing @firestitch/component-tools@18.0.18. 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.

Public source snippet (untrusted): ```json "postinstall": "node postinstall.js" ``` ### 11. High: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 99.0% - **Path:** postinstall.js - **Public source:** [View source]() The install hook deinitializes and removes the consumer's .vscode Git submodule, commits the removal, and pushes it to the configured remote.
