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 exported ESLint configuration performs undisclosed host and environment collection on import. It transmits that data to a remote endpoint. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-25T18:53:02.969Z - **Finished:** 2026-09-25T18:53:30.424Z - **Download time:** 252 ms - **Static scan time:** 8 ms - **AI review time:** 27195 ms - **Total time:** 27455 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 exported ESLint configuration performs undisclosed host and environment collection on import. It transmits that data to a remote endpoint. - **Trigger:** Loading the package as an ESLint configuration imports index.js. - **Impact:** Host identity, username, working directory, and CI or repository context can be disclosed to the remote operator. - **Evidence paths:** package.json, index.js - **Review source:** ai\_review - **Reviewed:** 2026-09-25T18:53:30.424Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The entrypoint collects system and CI metadata, encodes it as a query string, and issues an HTTPS GET request. - **Attack narrative:** When ESLint loads this configuration, the package entrypoint gathers machine and CI context, including hostname, username, current directory, and repository-related environment data. It then sends the encoded values to a remote AWS API endpoint. This behavior is unrelated to providing lint rules and occurs automatically on import. - **Rationale:** The package automatically exfiltrates host and CI metadata from its active configuration entrypoint to an unrelated endpoint. This is concrete malicious data collection rather than configuration behavior. - **Files touched:** index.js - **Network endpoints:** https://cbrsuo9293.execute-api.us-east-1.amazonaws.com/ ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The manifest makes index.js the package entrypoint., Importing the entrypoint collects host, user, runtime, working-directory, and CI-related environment information., The collected information is encoded and sent to an unrelated remote endpoint through HTTPS. ## Affected versions and remediation This report applies to eslint-config-compact-base@1.0.0. - Avoid installing eslint-config-compact-base@1.0.0. 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.
