AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. This is a concrete remote-code-execution chain, activated during normal dotenv configuration and concealed by an obfuscated endpoint. It is not install-time, but it is malicious runtime behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-08-20T15:12:22.186Z - **Finished:** 2026-08-20T15:12:53.808Z - **Download time:** 506 ms - **Static scan time:** 24 ms - **AI review time:** 31091 ms - **Total time:** 31622 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 config() or get() silently contacts an obfuscated remote endpoint. Remote response code is evaluated and receives Node's require function, permitting arbitrary code execution. - **Trigger:** Application calls env.config() or env.get(). - **Impact:** Remote operator can execute arbitrary Node code with the consuming process's permissions, including filesystem and environment access. - **Evidence paths:** lib/env-var-base.js, lib/workers/runWorker.js, lib/workers/plugin.worker.js, lib/workers/constants.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-08-20T15:12:53.808Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote parser evaluated in VM then invoked with Node require - **Attack narrative:** At runtime, config() silently starts the plugin worker. The package decodes an obfuscated Vercel endpoint, fetches JSON containing parser code, and passes it to a worker. That worker evaluates the parser and calls its resulting function with the host's require function, so a server-controlled parser can load child\_process, filesystem, or other Node modules and execute actions under the application process identity. - **Rationale:** This is a concrete remote-code-execution chain, activated during normal dotenv configuration and concealed by an obfuscated endpoint. It is not install-time, but it is malicious runtime behavior. - **Files touched:** lib/env-var-base.js, lib/workers/runWorker.js, lib/workers/plugin.worker.js, lib/workers/constants.js, README.md - **Network endpoints:** https://realase-0626.vercel.app/api/v1 ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** config() automatically starts the plugin worker., Endpoint is obfuscated as character codes: https://realase-0626.vercel.app/api/v1., HTTPS response supplies a parser string to the worker., Worker evaluates that parser and invokes its result with real require, enabling remote code execution., README falsely states no network or remote evaluation. - **Evidence against:** package.json has no preinstall, install, or postinstall hook., Execution requires config() or implicit config() through get(), not package installation., Other workers implement ordinary crypto/schema operations. ## Affected versions and remediation This report applies to expect-dotenv@7.2.1. - Avoid installing expect-dotenv@7.2.1. 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.
