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?
Read in glossary- 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.
Read in glossary- 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.
Read in glossary- 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
@azure-growth/signup-ux-components 1.2.2, 1.2.3 and 2.9.9 are dependency-confusion packages that take the name of a package used internally by Microsoft's Azure signup site and not published on the npm registry; 2.9.9 carries a version number above the internal release, so resolvers that also check the public registry prefer it. Their preinstall script runs node index.js, which reads the OS username and hostname and sends them in a DNS lookup of msrc-poc.<user>.<hostname>.dbg6vplohjpkmtolbi6g18ekofkxjzm4s.oast.fun, an out-of-band interaction collector; index.js is also the package entry point, so the lookup repeats whenever the package is required. Any machine that installed one of these versions has disclosed its username and hostname to a third party. The earlier 0.0.0-stage version is an inert placeholder and is not affected.

On npm install, the package's preinstall lifecycle hook executes index.js, which reads the installer's OS username (os.userInfo().username) and hostname (os.hostname()) and embeds them as labels in a subdomain under an interactsh out-of-band collector (dbg6vplohjpkmtolbi6g18ekofkxjzm4s.oast.fun), then triggers a DNS resolution for that name. The resulting DNS query transmits the installer's identity to the attacker-controlled DNS listener. The @azure-growth scope impersonates Microsoft/Azure internal naming, consistent with a dependency-confusion probe targeting an internal Azure package. The package provides no legitimate UI-component functionality to justify this behavior.
