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-2026-44210 exists.\n\nAffected packages and fixed versions:\n- github.com/kata-containers/kata-containers (Go): affected all versions; fixed in 0.0.0-20260519062212-ffa59ce3aa78\n- github.com/kata-containers/kata-containers (Go): affected all versions; fixed in 0.0.0-20260519062212-ffa59ce3aa78\n- github.com/kata-containers/kata-containers (Go): affected all versions; fixed in 0.0.0-20260519062212-ffa59ce3aa78\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-2026-44210/ (Markdown: https://insights.sbomify.com/CVE-2026-44210/index.md)","id":"CVE-2026-44210","markdown":"https://insights.sbomify.com/CVE-2026-44210/index.md","name":"CVE-2026-44210","record":{"aliases":["AZL-93063","AZL-93066","GHSA-rr59-xxvx-96qr","GO-2026-5638"],"analysis":{"component_type":"container_or_infrastructure","fix_type":"upgrade","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Kata Containers","requires_auth":"low_privilege","summary":"Attackers can escape VMs and access host files by injecting arguments into virtiofsd via default-enabled pod annotations in Kata Containers.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"kata_containers","vendor":"katacontainers"}],"cvss":{"score":5.8,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:N/SC:H/SI:H/SA:H/E:P","version":"4.0"},"cwes":[{"id":"CWE-88","name":"Improper Neutralization of Argument Delimiters in a Command"}],"description":"Kata Containers is an open source project focusing on a standard implementation of lightweight Virtual Machines (VMs) that perform like containers. Versions prior to 3.31.0 ship with a default configuration that allows pod creators to inject arbitrary command-line arguments into the virtiofsd process through the `io.katacontainers.config.hypervisor.virtio_fs_extra_args` pod annotation. By injecting `-o source=/` along with `--no-announce-submounts` and `--sandbox=none`, an attacker can override the virtiofsd shared directory to serve the entire host root filesystem into the guest VM. Combined with the `kernel_params` annotation (also enabled by default) to activate the agent debug console, the attacker can mount the host filesystem from inside the VM and read or write any file on the host, including /etc/shadow. Version 3.31.0 patches the issue.","ecosystems":["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":"Kata Containers have VM Escape via virtiofsd Argument Injection through Default-Enabled Pod Annotations","id":"CVE-2026-44210","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"command_injection","year":"2026"},"n_packages":3,"n_references":2,"next":{"headline":"Cline Kanban Server has a Cross-Origin WebSocket Hijacking Vulnerability","id":"CVE-2026-44211"},"packages":[{"ecosystem":"Go","fixed":["0.0.0-20260519062212-ffa59ce3aa78"],"introduced":["0"],"last_affected":[],"package":"github.com/kata-containers/kata-containers","purl":null,"source":"GHSA-rr59-xxvx-96qr"},{"ecosystem":"Go","fixed":["0.0.0-20260519062212-ffa59ce3aa78"],"introduced":["0"],"last_affected":[],"package":"github.com/kata-containers/kata-containers","purl":"pkg:golang/github.com/kata-containers/kata-containers","source":"GHSA-rr59-xxvx-96qr"},{"ecosystem":"Go","fixed":["0.0.0-20260519062212-ffa59ce3aa78"],"introduced":["0"],"last_affected":[],"package":"github.com/kata-containers/kata-containers","purl":"pkg:golang/github.com/kata-containers/kata-containers","source":"GO-2026-5638"}],"prev":{"headline":"Banks: Critical Remote Code Execution (RCE) via Jinja2 SSTI","id":"CVE-2026-44209"},"products":["kata-containers"],"published":"2026-07-23","related":[{"cvss_score":9.4,"headline":"Kata Container to Guest micro VM privilege escalation","id":"CVE-2026-24834","kev_date_added":null,"published":"2026-02-19"},{"cvss_score":8.8,"headline":"Other in kata-containers","id":"CVE-2026-24054","kev_date_added":null,"published":"2026-01-29"},{"cvss_score":8.8,"headline":"Code injection in n/a","id":"CVE-2020-27151","kev_date_added":null,"published":"2020-12-07"}],"sources":[{"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":"yes","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-07-24","vendors":["kata-containers"]},"summary":"Attackers can escape VMs and access host files by injecting arguments into virtiofsd via default-enabled pod annotations in Kata Containers.","url":"https://insights.sbomify.com/CVE-2026-44210/"}
