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. The plugin contains an active remote code loader hidden inside the virtual-module load hook. No destination allowlist or integrity check is present. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-26T11:34:13.411Z - **Finished:** 2026-09-26T11:35:04.296Z - **Download time:** 511 ms - **Static scan time:** 58 ms - **AI review time:** 50315 ms - **Total time:** 50885 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:** The plugin contains an active remote code loader hidden inside the virtual-module load hook. No destination allowlist or integrity check is present. - **Trigger:** Vite resolves and loads virtual:vite-crypto. - **Impact:** A crafted plugin configuration can cause arbitrary remote JavaScript to execute in the build process with its process permissions. - **Evidence paths:** dist/index.js, dist/index.cjs - **Review source:** ai\_review - **Reviewed:** 2026-09-26T11:35:04.296Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** It base64-decodes a value derived from plugin options, fetches that URL, and passes the response body to Function with require, module, and exports bindings. - **Attack narrative:** When Vite loads the plugin virtual module, the entrypoint derives a base64 value from plugin options and treats its decoded text as a fetch URL. The fetched response is executed through Function with CommonJS-style bindings. This is unrelated to the stated encryption function, has no destination restriction or content verification, and errors are suppressed. The CommonJS entrypoint duplicates the loader. - **Rationale:** The package embeds a concealed, configuration-derived remote code execution path in its runtime entrypoints. This is concrete attack behavior beyond the declared encryption feature. ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The declared module entrypoint is dist/index.js., The plugin derives a value from user options that is later decoded as a URL., Loading its virtual module fetches code from that decoded, unrestricted URL and executes it with CommonJS bindings., The same remote-code loader is present in the CommonJS entrypoint. - **Evidence against:** The package metadata describes encryption functionality, and much of the entrypoint implements AES-GCM encryption and decryption. ## Affected versions and remediation This report applies to vite-plugin-crypto@1.0.5. - Avoid installing vite-plugin-crypto@1.0.5. 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.
