It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-84200 exists.\n\nAffected packages and fixed versions:\n- github.com/kyverno/kyverno (Go): affected from 1.9.0; fixed in 1.13.0\n- github.com/kyverno/kyverno (Go): affected from 1.9.0; fixed in 1.13.0\n- github.com/kyverno/kyverno (Go): affected from 1.9.0; fixed in 1.13.0\n- kyverno (Bitnami): affected all versions; fixed in 1.13.0\n\nTask:\n1. 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.\n2. 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.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-84200/ (Markdown: https://insights.sbomify.com/CVE-2026-84200/index.md)","id":"CVE-2026-84200","markdown":"https://insights.sbomify.com/CVE-2026-84200/index.md","name":"CVE-2026-84200","record":{"aliases":["BIT-kyverno-2026-84200","GHSA-gg4x-fgg2-h9w9","GHSA-q8fv-357q-9mmj","GO-2026-4285","MINI-2hx7-wv3g-7j83","MINI-4j7g-jqxw-4cfq","MINI-75hc-r9wc-vcvp","MINI-8573-fhrj-mwh4","MINI-r8h5-x4fv-ghcm","MINI-xw49-6w7f-hf3w"],"analysis":{"component_type":"container_or_infrastructure","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Kubernetes policy engine","requires_auth":"low_privilege","summary":"Attackers can bypass Kyverno enforcement policies by exploiting exception precedence, allowing unauthorized resources like hostPath volumes.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":9.4,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:A/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H","version":"4.0"},"cwes":[{"id":"CWE-284","name":"Improper Access Control"}],"description":"Kyverno versions v1.9.0 through v1.12.7 contain a policy exception handling flaw.

This can be used to circumvent policies such as one blocking hostPath volumes.
