Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-41485 exists.\n\nAffected packages and fixed versions:\n- github.com/kyverno/kyverno (Go): affected from 1.13.0; fixed in 1.16.4, 1.17.2\n- github.com/kyverno/kyverno (Go): affected from 1.13.0; fixed in 1.16.4\n- github.com/kyverno/kyverno (Go): affected from 1.13.0; fixed in 1.16.4\n- github.com/kyverno/kyverno (Go): affected from 1.17.0-rc.1; fixed in 1.17.2\n- github.com/kyverno/kyverno (Go): affected from 1.17.0-rc.1; fixed in 1.17.2\n- kyverno (Bitnami): affected all versions; fixed in 1.16.4, 1.17.2\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-2026-41485/ (Markdown: https://insights.sbomify.com/CVE-2026-41485/index.md)","id":"CVE-2026-41485","markdown":"https://insights.sbomify.com/CVE-2026-41485/index.md","name":"CVE-2026-41485","record":{"aliases":["BIT-kyverno-2026-41485","ECHO-12c1-8179-4525","GHSA-fpjq-c37h-cqcv","GO-2026-5374","MINI-67v6-5g95-86fx","MINI-7w84-vc66-qf4x","MINI-96g6-rqj4-prpr","MINI-fcpv-pq26-g59r","MINI-g26q-hf86-gv3x","MINI-g64x-f39w-2x3p","MINI-g932-h364-jw74","MINI-gq76-4v74-cgqj","MINI-h633-28gc-9qh5","MINI-hm38-679p-8v4p","MINI-mprf-8jxx-79r6","MINI-p7rq-fp66-6cvf","MINI-r8c2-2r3p-gcq7"],"analysis":{"component_type":"container_or_infrastructure","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Kubernetes policy engine","requires_auth":"low_privilege","summary":"A user with policy creation permissions can crash the Kyverno controller via a type assertion panic, causing a persistent denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"kyverno","vendor":"kyverno"}],"cvss":{"score":7.7,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-617","name":"Reachable Assertion"}],"description":"Kyverno is a policy engine designed for cloud native platform engineering teams. Prior to versions 1.17.2 and 1.16.4, an unchecked type assertion in the `forEach` mutation handler allows any user with permission to create a `Policy` or `ClusterPolicy` to crash the cluster-wide background controller into a persistent CrashLoopBackOff. The same bug also causes the admission controller to drop connections and block all matching resource operations. The crash loop persists until the policy is deleted. The vulnerability is confined to the legacy engine, and CEL-based policies are unaffected. Versions 1.17.2 and 1.16.4 fix the issue.","ecosystems":["Bitnami","Go"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"Kyverno Controller Denial of Service via forEach Mutation Panic","id":"CVE-2026-41485","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":6,"n_references":3,"next":{"headline":"Ray: Remote Code Execution via Parquet Arrow Extension Type Deserialization","id":"CVE-2026-41486"},"packages":[{"ecosystem":"Bitnami","fixed":["1.16.4","1.17.2"],"introduced":["0","1.17.0"],"last_affected":[],"package":"kyverno","purl":"pkg:bitnami/kyverno","source":"BIT-kyverno-2026-41485"},{"ecosystem":"Go","fixed":["1.16.4","1.17.2"],"introduced":["1.13.0","1.17.0-rc.1"],"last_affected":[],"package":"github.com/kyverno/kyverno","purl":"pkg:golang/github.com/kyverno/kyverno","source":"GO-2026-5374"},{"ecosystem":"Go","fixed":["1.16.4"],"introduced":["1.13.0"],"last_affected":[],"package":"github.com/kyverno/kyverno","purl":null,"source":"GHSA-fpjq-c37h-cqcv"},{"ecosystem":"Go","fixed":["1.16.4"],"introduced":["1.13.0"],"last_affected":[],"package":"github.com/kyverno/kyverno","purl":"pkg:golang/github.com/kyverno/kyverno","source":"GHSA-fpjq-c37h-cqcv"},{"ecosystem":"Go","fixed":["1.17.2"],"introduced":["1.17.0-rc.1"],"last_affected":[],"package":"github.com/kyverno/kyverno","purl":null,"source":"GHSA-fpjq-c37h-cqcv"},{"ecosystem":"Go","fixed":["1.17.2"],"introduced":["1.17.0-rc.1"],"last_affected":[],"package":"github.com/kyverno/kyverno","purl":"pkg:golang/github.com/kyverno/kyverno","source":"GHSA-fpjq-c37h-cqcv"}],"prev":{"headline":"OpenTelemetry.Exporter.OneCollector vulnerable to denial of service via unbounded HTTP error response body","id":"CVE-2026-41484"},"products":["kyverno"],"published":"2026-04-24","related":[{"cvss_score":10,"headline":"Kyverno Cross-Namespace Privilege Escalation via Policy apiCall","id":"CVE-2026-22039","kev_date_added":null,"published":"2026-01-27"},{"cvss_score":9.8,"headline":"CVE-2026-4789","id":"CVE-2026-4789","kev_date_added":null,"published":"2026-03-30"},{"cvss_score":8.6,"headline":"Kyverno vulnerable to bypass of policy rules that use namespace selectors in match statements","id":"CVE-2025-46342","kev_date_added":null,"published":"2025-04-30"},{"cvss_score":8.1,"headline":"Kyverno: ServiceAccount token leaked to external servers via apiCall service URL","id":"CVE-2026-41323","kev_date_added":null,"published":"2026-04-24"},{"cvss_score":8.1,"headline":"kyverno apicall servicecall implicit bearer token injection leaks kyverno serviceaccount token","id":"CVE-2026-40868","kev_date_added":null,"published":"2026-04-21"},{"cvss_score":8.1,"headline":"kyverno verifyImages rule bypass possible with malicious proxy/registry","id":"CVE-2022-47633","kev_date_added":null,"published":"2022-12-23"},{"cvss_score":7.7,"headline":"Kyverno: Cross-Namespace Read Bypasses RBAC Isolation (CVE-2026-22039 Incomplete Fix)","id":"CVE-2026-41068","kev_date_added":null,"published":"2026-04-24"}],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"Bitnami","prefix":"BIT"},{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"Go Vulnerability Database","prefix":"GO"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-04-24","vendors":["kyverno"]},"summary":"A user with policy creation permissions can crash the Kyverno controller via a type assertion panic, causing a persistent denial of service.","url":"https://insights.sbomify.com/CVE-2026-41485/"}
