    Priority (0–325)

    The priority score is a consolidated metric that condenses several individual signals into a single, action-guiding ranking: technical severity (CVSS), exploitation likelihood (EPSS), known-exploited status (KEV) and the context of the affected asset. The aim is to answer the only truly important question in vulnerability management: what first?

    30.00 Methodology
    Exploit maturity

    An exploit is code or a technique that specifically uses a concrete vulnerability to force unintended behaviour — such as executing code or escalating privileges. It is the tool that turns a theoretical flaw into a practical attack.

    no public PoC known
    KEV status

    The KEV catalogue is a list maintained by the US authority CISA of vulnerabilities for which active exploitation in the wild has been confirmed. It answers not the question „how severe?“ but „is it already being attacked?“ — thereby sharply prioritising patching.

    Classification under NIS2 and CRA

    Rule-based classification from exploitation status and severity. It does not replace a case-by-case assessment.

    NIS2

    NIS2 is EU Directive (EU) 2022/2555 to raise the level of cybersecurity across the Union. It substantially broadens obligations compared with the first NIS directive: more sectors, mandatory risk management, staged reporting duties and personal accountability of senior management.

    High technical severity: assess and remediate the vulnerability in vulnerability handling under Art. 21(2)(e) NIS2 and document the decision.
    CRA

    The CRA is EU Regulation (EU) 2024/2847 setting horizontal cybersecurity requirements for „products with digital elements“ — from industrial controllers and software to connected consumer devices. For the first time manufacturers must ensure security across the entire product lifecycle, handle vulnerabilities and provide security updates.

    Read in glossary
    From 11.12.2027, Annex I Part II CRA requires manufacturers of affected products with digital elements to handle vulnerabilities without delay and provide security updates.
    ISO/IEC 27001

    ISO/IEC 27001 is the internationally leading standard for an information security management system (ISMS). It describes a risk-based, process-oriented framework to systematically plan, implement, review and improve information security.

    Description

    identity-two-factor@999.0.0 is a dependency-confusion package aimed at Coinbase (its README and postinstall.js say so, and the beacon path is cbhq-canary) with no functional code. Its postinstall script runs node postinstall.js on npm install, which writes a marker file to the temp directory and POSTs the hostname, username, working-directory name, CI flag and Node version to https://webhook.site/e0981a8e-081e-49a0-8b4a-235109e13045/cbhq-canary. It was published by the npm account hologrammmm0x, which has no other packages.

    On npm install, postinstall.js collects os.hostname(), os.userInfo().username, the current working directory basename, a CI flag, and the Node version, and POSTs them to a hardcoded webhook.site URL (https://webhook.site/e0981a8e-081e-49a0-8b4a-235109e13045/cbhq-canary). The package is published at version 999.0.0 under a name that resembles an internal/private package, consistent with a dependency-confusion exfiltration payload: builds that resolve this public name over an intended private registry will automatically beacon identifying host and user metadata to a third-party collector endpoint. The in-source self-labeling as a 'security research canary' is author-controlled text and is not accompanied by any installer-visible authorization; the behavior itself is unsolicited data exfiltration from any machine that installs the package.
