Advisory PublishedCVSS 5.4/10

Vulnetix · Advisory published July 2, 2026

Hijacks browser pages that load zhuanhua@1.1.107 by injecting a full-screen iframe pointed at https://tckyv.ygh8tas.icu during browser execution. The payload is triggered by DOMContentLoaded or the immediate document.readyState path, not by an npm install hook. Trigger: browser on-use via DOMContentLoaded or the immediate document.readyState path in loaders/px.js:1. Chain: loaders/px.js:1 defines the hardcoded URL array, selects it into externalUrl, passes externalUrl to loadExternalContent, then assigns frame.src = url and appends the iframe to document.body. UI impact: creates a full-viewport fixed-position iframe at z-index:2147483647 that covers the page. The active attack-path IOC is https://tckyv.ygh8tas.icu during browser execution.
