Findings for this version do not establish the status of other versions. AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. The postinstall hook mutates the consumer project by creating \`src\`, but the guarded, non-overwriting copy matches the package's TypeScript Express starter purpose. Inspected runtime code connects to the configured MongoDB service, and no concrete malicious behavior was identified. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-11T23:57:59.117Z - **Finished:** 2026-10-11T23:58:19.347Z - **Download time:** 765 ms - **Static scan time:** 52 ms - **AI review time:** 19412 ms - **Total time:** 20230 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:** Installation can create a \`src\` directory in the consumer project by recursively copying this package's source tree when the directory is absent. The inspected application code uses its configured MongoDB connection when its server is started. - **Trigger:** Installing the package with a project directory supplied through \`INIT\_CWD\`; database connection occurs when the copied server is started. - **Impact:** This can add application source files to the consumer project during installation. No separate malicious attack behavior was established in the inspected source. - **Review source:** ai\_review - **Reviewed:** 2026-10-11T23:58:19.347Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The postinstall script copies the package's source tree into the consumer project if that project has no \`src\` directory. The server code reads a MongoDB URI from the environment and connects to it on startup. - **Rationale:** The postinstall hook mutates the consumer project by creating \`src\`, but the guarded, non-overwriting copy matches the package's TypeScript Express starter purpose. Inspected runtime code connects to the configured MongoDB service, and no concrete malicious behavior was identified. - **Files touched:** src ### Review decision - **Verdict:** Clean - **Confidence:** 91.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The postinstall hook runs a script that targets the installing project directory., The hook recursively copies the package's source tree into the consumer's \`src\` directory only when that directory is absent., The copied application reads a MongoDB URI from the environment, defaulting to localhost, and connects to that configured database when its server starts. - **Evidence against:** The inspected hook does not overwrite an existing consumer \`src\` directory., The inspected source shows no unrelated network destination or credential forwarding. ## Affected versions and remediation This report applies to @yes20sh/ts-node-express@1.0.1. - Review the evidence and your use of @yes20sh/ts-node-express@1.0.1 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.
