Cross-Site Scripting (XSS) in github.com/kyverno/policy-reporter-ui (CVE-2026-44245)
Summary
Cross-site scripting in github.com/kyverno/policy-reporter-ui (CVE-2026-44245). Risk of unauthorized operations or information disclosure. Mitigation: upgrade to 2.5.2+incompatible or later.
Original description
The description as published by the source.
Kyverno is a policy engine designed for cloud native platform engineering teams. Prior to 2.5.2, Vue 3's v-html directive is the framework-documented mechanism for injecting raw HTML, and it intentionally disables the auto-escaping that {{ }} interpolation provides. The PropertyCard.vue component uses v-html for the else branch of the URL check, meaning any non-URL string value flows directly into the DOM as HTML. The isURL() guard only filters values that parse as http: or https: URLs, so any HTML payload not starting with those schemes bypasses it entirely. The data originates from Kubernetes PolicyReport .results[].properties fields, which are arbitrary string maps populated by policy engines and potentially by any principal with write access to PolicyReport objects in the cluster. This vulnerability is fixed in 2.5.2.
