Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Blocked & quarantined** — The publisher’s feed host receives a credential that is also used to validate the license with Polar. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Matched malicious - **Public report status:** Published - **Threat category:** Credential Exfiltration - **Selected version:** 0.1.5 - **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 source shows an ordinary CLI invocation can forward a license credential to a publisher-selected host outside the service used to validate it. This is concrete credential disclosure, so block publication. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 97.0% - **Started:** 2026-10-24T12:31:45.965Z - **Finished:** 2026-10-24T12:32:18.990Z - **Download time:** 764 ms - **Static scan time:** 52 ms - **AI review time:** 32208 ms - **Total time:** 33025 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 can disclose a saved or environment-provided license credential to the publisher’s rules-feed host during startup. - **Trigger:** Running the CLI when a license key is available and no fresh feed cache is present. - **Impact:** The publisher’s feed host receives a credential that is also used to validate the license with Polar. - **Evidence paths:** package.json, cli.js, license.js - **Review source:** ai\_review - **Reviewed:** 2026-10-24T12:32:18.990Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Startup invokes the feed helper, which appends the license key to a request URL sent to getreadystack.com. - **Attack narrative:** The command-line entrypoint requests the rules feed before handling the user’s command. When a license key is available and the cached feed is stale, the helper sends that key in the query string to getreadystack.com; the same key is used with Polar’s license-validation service. The request has no recipient-specific consent gate. - **Rationale:** The source shows an ordinary CLI invocation can forward a license credential to a publisher-selected host outside the service used to validate it. This is concrete credential disclosure, so block publication. - **Files touched:** license.js - **Network endpoints:** https://getreadystack.com/api/rules/, https://api.polar.sh/v1/customer-portal/license-keys/validate ### Review decision - **Verdict:** Malicious - **Confidence:** 97.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The manifest exposes cli.js as the package command-line entry point., The CLI fetches the rules feed before processing its command-line arguments., The feed helper reads the license key from the environment or saved state and sends it as a query parameter to getreadystack.com., The same license key is submitted to Polar’s license-validation endpoint, establishing its credential use., No recipient-specific consent gate protects the feed request when a key is present and the feed cache is stale. ## Affected versions and remediation This report applies to @readystack/security-headers-csp-lint@0.1.5. - Avoid installing @readystack/security-headers-csp-lint@0.1.5. 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.
