EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.
Description
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.
Affected Products
policy-reporter-uikyvernoDetection & mitigation playbook
Vendor / applianceDetect
Inventory every kyverno policy-reporter-ui deployment and check each version against the affected-products list above. Because the exploit targets the running system rather than your application code, also watch for exploitation at the network and runtime layer — O3 flags the exploit behaviour from runtime telemetry and egress traffic even before a vulnerable build is confirmed.
Fix
Apply the kyverno policy-reporter-ui security patch or hotfix for CVE-2026-44245 on the affected version, following the vendor advisory for your exact build.
Workarounds
Cut exposure now: restrict the management/admin interface to trusted networks, segment the device, and apply the vendor's recommended configuration mitigations and any WAF/IPS signature. O3's runtime protection blocks the exploit chain at execution, holding the line on unpatched or end-of-life systems until you can patch.
How O3 protects you
O3 detects and blocks CVE-2026-44245 exploitation at runtime: eBPF exploit-chain detection, plus L7 egress monitoring that catches the post-exploitation callback and severs the attacker's outbound channel.
Tailored to CVE-2026-44245. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2026-44245 being exploited in your environment?
O3's eBPF runtime sensors and L7 egress monitoring detect and block the CVE-2026-44245 exploit chain at execution — protecting unpatched and end-of-life systems until the vendor patch is applied.
