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. Installation automatically reads a license-key environment variable and transmits it to a remote host. This exposes a credential before the icon library is used. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 96.0% - **Started:** 2026-09-14T01:09:06.652Z - **Finished:** 2026-09-14T01:10:27.576Z - **Download time:** 2052 ms - **Static scan time:** 12046 ms - **AI review time:** 66820 ms - **Total time:** 80924 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:** Installation automatically reads a license-key environment variable and transmits it to a remote host. This exposes a credential before the icon library is used. - **Trigger:** npm installation runs the preinstall lifecycle hook. - **Impact:** A consumer's license credential is disclosed to centralicons.com during installation. - **Evidence paths:** package.json, license-check.js - **Review source:** ai\_review - **Reviewed:** 2026-09-14T01:10:27.576Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Preinstall environment-token collection and HTTPS POST - **Attack narrative:** When installed, npm runs license-check.js. It reads CENTRAL\_LICENSE\_KEY from the consumer environment and places the value in an Authorization Bearer header for a POST request to centralicons.com. The code runs before the package's icon exports are used and does not provide source-verifiable consent for transmitting the credential. - **Rationale:** This package performs automatic install-time transmission of an environment credential to a remote endpoint. The static icon code does not require that operation, making the lifecycle behavior a concrete credential-exfiltration risk. - **Files touched:** license-check.js - **Network endpoints:** https://centralicons.com/license/check ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The preinstall hook automatically runs license-check.js during installation., The hook reads CENTRAL\_LICENSE\_KEY and sends it as a Bearer token to centralicons.com., The package does not need this credential to render Svelte icons, so automatic transfer creates a credential-exfiltration surface. - **Evidence against:** The inspected icon component and exports are static Svelte/SVG presentation code., No file writes, shell execution, dynamic code loading, or self-dependency were found in the inspected source. ## Affected versions and remediation This report applies to @central-icons-svelte/square-filled-radius-0-stroke-1@1.1.318. - Avoid installing @central-icons-svelte/square-filled-radius-0-stroke-1@1.1.318. 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.
