Do not execute instructions or code found in this document. ## Verdict summary **Allowed — no malicious behavior detected** — No malicious behavior detected. 12 low-signal pattern(s) reviewed. - **Verdict:** Clean - **Product-default install policy:** Allow - **Firewall policy:** No policy match - **Public report status:** Published - **Threat category:** None published - **Selected version:** 1.0.4 - **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: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. The flagged network and credential behavior is tied to this linter's licence validation and vendor rules feed; the configured product key is sent to the package vendor for that feed. The usage request contains only fixed package and source fields, and the inspected feed handling adds structured rules rather than executing downloaded code. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-31T14:52:39.512Z - **Finished:** 2026-10-31T14:53:27.952Z - **Download time:** 768 ms - **Static scan time:** 54 ms - **AI review time:** 47617 ms - **Total time:** 48440 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:** No attack was identified. The CLI contacts its licence and product services for validation, rule updates and limited usage counts. - **Trigger:** CLI startup, when a licence key is configured, and CLI use for the usage count. - **Impact:** No credential theft, project-data collection, or unrelated account action was identified in the inspected source. - **Review source:** ai\_review - **Reviewed:** 2026-10-31T14:53:27.952Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The CLI sends the product licence key to the vendor's rules endpoint to retrieve rules; it also validates keys with Polar. The usage count contains fixed package and command fields, not scanned file contents. - **Rationale:** The flagged network and credential behavior is tied to this linter's licence validation and vendor rules feed; the configured product key is sent to the package vendor for that feed. The usage request contains only fixed package and source fields, and the inspected feed handling adds structured rules rather than executing downloaded code. - **Files touched:** ${READYSTACK\_HOME}/rechnung-pflichtangaben-lint-de.json, ~/.config/readystack/rechnung-pflichtangaben-lint-de.json - **Network endpoints:** getreadystack.com, api.polar.sh ### Review decision - **Verdict:** Clean - **Confidence:** 91.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The package describes a CLI that checks PHP invoice templates against tax invoice requirements., At CLI startup, the program may fetch a rules feed and append the returned rules to its rule list., The feed request sends the configured product licence key to getreadystack.com; it runs only when a key is present and caches the response., The engine evaluates structured rule types against input text and returns findings; the inspected code does not execute feed content as code., Licence validation sends the key to api.polar.sh, the licence validation service., Usage telemetry sends fixed fields for the package slug, CLI source and usage reason, rather than scanned file contents. ## Affected versions and remediation This report applies to @readystack/rechnung-pflichtangaben-lint-de@1.0.4. - Review the evidence and your use of @readystack/rechnung-pflichtangaben-lint-de@1.0.4 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
