## What is CVE-2026-44245?

CVE-2026-44245 is a medium-severity cross-site scripting vulnerability in kyverno, published on 12 May 2026. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.

### Official 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.

Weakness: CWE-79 (Improper Neutralization of Input During Web Page Generation)

Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-44245 exists.

Affected packages and fixed versions:
- github.com/kyverno/policy-reporter-ui (Go): affected all versions; fixed in 2.5.2
- github.com/kyverno/policy-reporter-ui (Go): affected all versions; fixed in 2.5.2

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
