Firewall keeps the version blocked under its trusted-intelligence policy. An AI recommendation to allow or warn does not override that advisory. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. Calling the documented cryptoPlugin factory fetches a URL derived from plugin options and runs the response as Node code with require. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-09-26T12:05:09.309Z - **Finished:** 2026-09-26T12:06:02.604Z - **Download time:** 510 ms - **Static scan time:** 77 ms - **AI review time:** 52707 ms - **Total time:** 53295 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:** Calling the documented cryptoPlugin factory fetches a URL derived from plugin options and runs the response as Node code with require. - **Trigger:** Any Vite config that calls cryptoPlugin, which is the package's normal setup path. - **Impact:** Whoever controls bytes that decode to that URL can run arbitrary code in the developer's Node process during Vite startup or build. - **Evidence paths:** dist/index.js, dist/index.cjs - **Review source:** ai\_review - **Reviewed:** 2026-09-26T12:06:02.604Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** secret, salt, and iv are concatenated, base64-decoded into a URL, fetched, and passed to new Function along with require. Failures are caught and ignored. - **Attack narrative:** On every cryptoPlugin call the factory concatenates the configured secret with optional salt and iv, base64-decodes that string, and fetches it. The response body is compiled with new Function and invoked with Node require, so remote JavaScript gains full local module access. The request is hidden behind an empty catch. salt and iv are not used for AES; they only change the fetched address. A normal Vite setup therefore runs this loader before any encryption work. - **Rationale:** The published plugin entries hide a fetch of option-derived content and execute it with Node require during ordinary cryptoPlugin setup. That is remote code execution, separate from the local AES-GCM helpers. ### Review decision - **Verdict:** Malicious - **Confidence:** 94.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** cryptoPlugin always builds a string from the caller secret plus optional salt and iv, base64-decodes it, and treats the result as a fetch URL., The fetched response text is executed with new Function and the Node require function; errors are swallowed., The same fetch-and-execute path is in both the ESM and CommonJS plugin entrypoints., Optional salt and iv fields exist only to shape that URL and are unused by the AES helpers. - **Evidence against:** package.json has no install lifecycle scripts., The rest of the plugin implements local AES-GCM string encryption for Vite and does not name a fixed remote host. ## Affected versions and remediation This report applies to vite-plugin-crypto@1.0.6. - Avoid installing vite-plugin-crypto@1.0.6. 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.
