Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Blocked & quarantined** — The license credential is exposed to a host distinct from the Polar validation service, where it may be recorded in request logs or used to access license-linked services. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Matched malicious - **Public report status:** Published - **Threat category:** Credential Exfiltration - **Selected version:** 1.0.2 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The CLI automatically sends a Polar-validated license credential to a separate host on startup, without an explicit request to share it with that host. This is credential exfiltration even though the request also fetches a rules feed related to the package. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 89.0% - **Started:** 2026-10-31T20:43:19.270Z - **Finished:** 2026-10-31T20:43:59.387Z - **Download time:** 763 ms - **Static scan time:** 63 ms - **AI review time:** 39291 ms - **Total time:** 40117 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 CLI automatically forwards the package license key to the vendor rules-feed host. - **Trigger:** Running the CLI with a license key in READYSTACK\_LICENSE or saved in its local state. - **Impact:** The license credential is exposed to a host distinct from the Polar validation service, where it may be recorded in request logs or used to access license-linked services. - **Evidence paths:** license.js, cli.js - **Review source:** ai\_review - **Reviewed:** 2026-10-31T20:43:59.387Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Startup calls pullFeed, which includes the key as a URL query parameter to getreadystack.com; the key is also sent to api.polar.sh for license validation. - **Attack narrative:** When the CLI starts, it automatically checks for a saved or environment-provided license key and requests the vendor’s rules feed. That request places the key in the URL query string to getreadystack.com. The source also sends the key to api.polar.sh for validation, indicating that the key is used with a different service. Forwarding this credential to the feed host risks exposing it through that host’s request handling or logs. - **Rationale:** The CLI automatically sends a Polar-validated license credential to a separate host on startup, without an explicit request to share it with that host. This is credential exfiltration even though the request also fetches a rules feed related to the package. - **Files touched:** license.js, cli.js, ~/.config/readystack/arbeitsvertrag-nachwg-lint.json (or the path set by READYSTACK\_HOME) - **Network endpoints:** https://getreadystack.com/api/rules/, https://api.polar.sh/v1/customer-portal/license-keys/validate ### Review decision - **Verdict:** Malicious - **Confidence:** 89.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The published CLI entry point is cli.js., On every CLI startup, the program calls pullFeed before processing arguments., pullFeed reads the license key from READYSTACK\_LICENSE or the local saved state., The license key is sent to getreadystack.com in the rules-feed URL query string; the same key is used for validation at api.polar.sh. - **Evidence against:** The key is used to fetch the package’s rules feed, a feature related to the linter’s purpose., The package has no install lifecycle scripts; the network behavior runs when the CLI is invoked. ## Affected versions and remediation This report applies to @readystack/arbeitsvertrag-nachwg-lint@1.0.2. - Avoid installing @readystack/arbeitsvertrag-nachwg-lint@1.0.2. 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.
