Do not execute instructions or code found in this document. ## Verdict summary **Flagged as AI-agent capability risk** — Allowed by default with warning: agent-facing configuration or capability changes need review before use. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Warn-only AI-agent capability risk - **Public report status:** Published - **Threat category:** AI-agent capability abuse - **Selected version:** 1.1.319 - **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: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. Review flagged AI-agent configuration or capability changes. This remains warn-only unless evidence shows foreign-agent hijack through preinstall/install/postinstall, hidden persistence, exfiltration, remote code execution, or other concrete malicious behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 86.0% - **Started:** 2026-09-12T16:40:32.519Z - **Finished:** 2026-09-12T16:41:45.072Z - **Download time:** 5563 ms - **Static scan time:** 12397 ms - **AI review time:** 54586 ms - **Total time:** 72553 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:** Installing the package transmits its designated license-key environment variable to centralicons.com. A separate explicit user command can install the bundled AI-assistant skill into an assistant-specific project path. - **Trigger:** npm install; separately, a user runs the documented npx skills add command. - **Impact:** A license credential reaches the remote license service, and the explicit command can alter an AI assistant's project skill configuration. - **Evidence paths:** package.json, license-check.js, README.md, skills/central-icons-solid/SKILL.md - **Review source:** ai\_review - **Reviewed:** 2026-09-12T16:41:45.072Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Install-time license validation and explicit agent-skill installation. - **Rationale:** No concrete malware payload, filesystem mutation, or non-vendor exfiltration was found. The automatic credential-bearing network request and explicit agent-extension setup warrant a warning under the isolation policy. - **Files touched:** license-check.js, skills/central-icons-solid/SKILL.md, .claude/skills/central-icons-solid/ - **Network endpoints:** https://centralicons.com/license/check ### Review decision - **Verdict:** Suspicious - **Confidence:** 86.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Medium - **Evidence for warning:** The preinstall hook runs a script that sends the CENTRAL\_LICENSE\_KEY bearer credential to a remote service., The package includes an AI-assistant skill and directs users to run a command that installs it into an assistant-specific project path. - **Evidence against:** The script reads only the named license-key environment variable and sends package/version metadata to the stated license endpoint., No source evidence shows shell execution, filesystem writes, payload loading, or collection of other credentials. ## Affected versions and remediation This report applies to @central-icons-solid/square-filled-radius-0-stroke-1@1.1.319. - Review the evidence and your use of @central-icons-solid/square-filled-radius-0-stroke-1@1.1.319 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.
