Cloudflare launches Zero Wire vulnerability intelligence feed on Radar

Cloudflare has introduced Zero Wire, a public vulnerability intelligence feed on Cloudflare Radar for critical Internet-facing software vulnerabilities. Each briefing offers plain-language summaries, recommended actions, links to evidence and vendor guidance, and an AI-agent prompt for assessing infrastructure exposure. The feed is intended to help security teams understand significant vulnerabilities and decide what to do next.

How Zero Wire works

Zero Wire lives inside Cloudflare Radar under the security section. Each briefing brings together a plain-language explanation, who should investigate, recommended actions, and links to evidence and vendor guidance. Cloudflare contributes security research, network observations, and practical control knowledge, while also linking to authoritative external sources.

Focus and categories

Rather than listing every CVE, Zero Wire focuses on critical CVEs in Internet-facing software, including web applications, runtimes, libraries, and exposed services. The homepage separates briefings into Needs attention and Reference categories. A WAF rule is not a prerequisite for inclusion, and some issues require vendor updates beyond traffic Cloudflare can inspect.

Evidence and Cloudflare context

Each briefing links to external documents such as CVE records, research, and exploitation evidence, including CISA's Known Exploited Vulnerabilities Catalog. Cloudflare may add network traffic context, such as WAF rule matches, but observing attempts does not establish compromise. The Cloudflare section explains available compensating controls and configuration requirements, while noting WAF mitigation is not a replacement for fixing vulnerable software.

Staying informed

Briefings include update chronology and last-checked dates to show developments since a previous visit. Zero Wire also provides an AI-agent prompt for read-only assessment of deployed software, vendor fixes, exposure, and compensating controls. Cloudflare says the goal is to reduce time spent assembling basic facts and help teams act on disclosures.
