    CVE-2026-84196

    Kyverno before 1.18.0 contains a server-side request forgery vulnerability in apiCall.service.url that allows authenticated users to send arbitrary HTTP requests by injecting user-controlled input through variable substitution. Attackers can target internal services, cloud metadata endpoints, and loopback addresses, with response data reflected in admission error messages enabling non-blind data exfiltration.
