An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-62440 in the wild and no public exploit code.\n\nAffected product: Apache Cloudstack. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2026-62440/ (Markdown: https://insights.sbomify.com/CVE-2026-62440/index.md)","id":"CVE-2026-62440","markdown":"https://insights.sbomify.com/CVE-2026-62440/index.md","name":"CVE-2026-62440","record":{"aliases":["GHSA-2vq4-5w2v-frrg"],"analysis":{"component_type":"cloud_service","fix_type":"upgrade","impacts":["privilege_escalation","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"CloudStack CKS plugin","requires_auth":"none","summary":"Attackers can manipulate Kubernetes clusters across tenants by adding or removing nodes due to improper access control in the CKS plugin.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"cloudstack","vendor":"apache"}],"cvss":{"score":9.1,"severity":"critical","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-284","name":"Improper Access Control"}],"description":"Improper Access Control vulnerability in Apache CloudStack's Kubernetes Service (CKS) plugin, allowing cross-tenant manipulation of the Kubernetes cluster while adding and removing nodes.\n\nThis issue affects Apache CloudStack: from 4.21.0.0 through 4.22.1.0.\n\nUsers are recommended to upgrade to version 4.22.1.1 or later, which fixes the issue.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Apache CloudStack: Improper access control in Kubernetes Service (CKS) cluster manipulation","id":"CVE-2026-62440","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"apache:cloudstack","products":["apache:cloudstack"],"type":"missing_authorization","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Missing authorization in Oracle Hyperion Calculation Manager","id":"CVE-2026-62441"},"packages":[],"prev":{"headline":"Gimp: gimp: file-pvr plug-in pvr file parsing integer overflow heap-based buffer overflow vulnerability","id":"CVE-2026-62439"},"products":["Apache CloudStack"],"published":"2026-08-21","related":[{"cvss_score":10,"headline":"Missing authorization in n/a","id":"CVE-2012-4501","kev_date_added":null,"published":"2012-10-26"},{"cvss_score":9.8,"headline":"Apache CloudStack: Unauthenticated cluster service port leads to remote execution","id":"CVE-2024-38346","kev_date_added":null,"published":"2024-07-05"},{"cvss_score":9.8,"headline":"Apache CloudStack: Integration API service uses dynamic port when disabled","id":"CVE-2024-39864","kev_date_added":null,"published":"2024-07-05"},{"cvss_score":9.8,"headline":"Apache CloudStack: x-forwarded-for HTTP header parsed by default","id":"CVE-2024-29006","kev_date_added":null,"published":"2024-04-04"},{"cvss_score":9.8,"headline":"Apache CloudStack SAML Single Sign-On XXE","id":"CVE-2022-35741","kev_date_added":null,"published":"2022-07-18"},{"cvss_score":9.8,"headline":"Command injection in Apache CloudStack","id":"CVE-2019-17562","kev_date_added":null,"published":"2020-05-14"},{"cvss_score":9.8,"headline":"Missing authorization in Apache CloudStack","id":"CVE-2016-6813","kev_date_added":null,"published":"2018-02-06"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-08-25","vendors":["Apache Software Foundation"]},"summary":"Attackers can manipulate Kubernetes clusters across tenants by adding or removing nodes due to improper access control in the CKS plugin.","url":"https://insights.sbomify.com/CVE-2026-62440/"}
