It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-19444 in the wild and no public exploit code.\n\nAffected product: Kubernetes. 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-2026-19444/ (Markdown: https://insights.sbomify.com/CVE-2026-19444/index.md)","id":"CVE-2026-19444","markdown":"https://insights.sbomify.com/CVE-2026-19444/index.md","name":"CVE-2026-19444","record":{"aliases":["AZL-105173","GHSA-pw89-p422-jr5j","MINI-f886-px58-5mfq","MINI-h2q7-gvr4-mm23","MINI-p48g-f78v-pr7f","MINI-r533-8cp4-59cf","MINI-vmrf-w668-73j4","MINI-xg95-h87p-7p8q","OESA-2026-4460","OESA-2026-4461","OESA-2026-4462","OESA-2026-4463"],"analysis":{"component_type":"developer_tool","fix_type":"patch","impacts":["code_execution","data_modify"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Kubernetes kubectl client","requires_auth":"high_privilege","summary":"A malicious container can write arbitrary files to the local Windows machine via kubectl cp, potentially leading to code execution or data modification.","user_interaction":"required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"kubernetes","cpe":[],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:H/UI:R/S:C/C:L/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"A path traversal vulnerability was discovered in the Kubernetes kubectl client's kubectl cp command on Windows. When copying files from a container, kubectl runs tar inside the container to build a tar archive, transfers it over the network, and unpacks it on the local machine. If the tar binary in the container is malicious, it can execute arbitrary code and emit unexpected output, allowing an attacker who controls container contents to write files to arbitrary paths on the user's local machine when kubectl cp is invoked, limited only by the system permissions of the local user. This issue only affects kubectl clients running on Windows.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Kubernetes kubectl cp path traversal on Windows allows arbitrary file writes","id":"CVE-2026-19444","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"path_traversal","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"Use-after-free of a server-side SSLContext when sni_callback switches contexts","id":"CVE-2026-19445"},"packages":[],"prev":{"headline":"Vulnerabilities in IBM AIX and PowerVM VIOS","id":"CVE-2026-19442"},"products":["Kubernetes"],"published":"2026-09-28","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-09-28","vendors":["Kubernetes"]},"summary":"A malicious container can write arbitrary files to the local Windows machine via kubectl cp, potentially leading to code execution or data modification.","url":"https://insights.sbomify.com/CVE-2026-19444/"}
