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-2026-41323 exists.\n\nAffected packages and fixed versions:\n- github.com/kyverno/kyverno (Go): affected all versions; fixed in 1.17.0\n- github.com/kyverno/kyverno (Go): affected all versions; fixed in 1.17.0\n- github.com/kyverno/kyverno (Go): affected all versions; fixed in 1.17.0\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-2026-41323/ (Markdown: https://insights.sbomify.com/CVE-2026-41323/index.md)","id":"CVE-2026-41323","markdown":"https://insights.sbomify.com/CVE-2026-41323/index.md","name":"CVE-2026-41323","record":{"aliases":["BIT-kyverno-2026-41323","ECHO-c76c-b1c4-8843","GHSA-f9g8-6ppc-pqq4","GO-2026-5351","MINI-4vhr-7vhf-hw33","MINI-68vw-hcv3-3rmq","MINI-6fh3-c84g-63rv","MINI-7v35-f3jm-2mpm","MINI-876x-4x3g-v27x","MINI-87cq-g3hp-62r7","MINI-f9g3-xrvp-f2q8","MINI-gg5q-hqjr-4mrr","MINI-gpg8-mr95-6gp4","MINI-j5vm-cjmc-97v4","MINI-jv4w-mpm6-hvpp","MINI-jx4r-9m38-mv7p","MINI-pgp3-xcjr-x529","MINI-wpm6-7xpx-mww2","MINI-xxmr-rrqc-25px"],"analysis":{"component_type":"container_or_infrastructure","fix_type":"upgrade","impacts":["privilege_escalation","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Kubernetes policy engine","requires_auth":"low_privilege","summary":"Attackers can steal ServiceAccount tokens via unvalidated apiCall URLs, leading to full Kubernetes cluster compromise.","user_interaction":"not_required","vuln_class":"ssrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"kyverno","vendor":"kyverno"}],"cvss":{"score":8.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-918","name":"Server-Side Request Forgery"},{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"description":"Kyverno is a policy engine designed for cloud native platform engineering teams. Prior to versions 1.18.0-rc1, 1.17.2-rc1, and 1.16.4, Kyverno's apiCall feature in ClusterPolicy automatically attaches the admission controller's ServiceAccount token to outgoing HTTP requests. The service URL has no validation — it can point anywhere, including attacker-controlled servers. Since the admission controller SA has permissions to patch webhook configurations, a stolen token leads to full cluster compromise. Versions 1.18.0-rc1, 1.17.2-rc1, and 1.16.4 patch 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: ServiceAccount token leaked to external servers via apiCall service URL","id":"CVE-2026-41323","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":null,"products":[],"type":"ssrf","year":"2026"},"n_packages":4,"n_references":4,"next":{"headline":"basic-ftp vulnerable to denial of service via unbounded memory consumption in Client.list()","id":"CVE-2026-41324"},"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-2026-41323"},{"ecosystem":"Go","fixed":["1.17.0"],"introduced":["0"],"last_affected":[],"package":"github.com/kyverno/kyverno","purl":null,"source":"GHSA-f9g8-6ppc-pqq4"},{"ecosystem":"Go","fixed":["1.17.0"],"introduced":["0"],"last_affected":[],"package":"github.com/kyverno/kyverno","purl":"pkg:golang/github.com/kyverno/kyverno","source":"GHSA-f9g8-6ppc-pqq4"},{"ecosystem":"Go","fixed":["1.17.0"],"introduced":["0"],"last_affected":[],"package":"github.com/kyverno/kyverno","purl":"pkg:golang/github.com/kyverno/kyverno","source":"GO-2026-5351"}],"prev":{"headline":"@astrojs/node: Cache Poisoning due to incorrect error handling when if-match header is malformed","id":"CVE-2026-41322"},"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 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":"total"},"state":"PUBLISHED","updated":"2026-04-24","vendors":["kyverno"]},"summary":"Attackers can steal ServiceAccount tokens via unvalidated apiCall URLs, leading to full Kubernetes cluster compromise.","url":"https://insights.sbomify.com/CVE-2026-41323/"}
