It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-67499 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/containernetworking/plugins (Go): affected from 1.6.0; fixed in 1.9.0\n- github.com/containernetworking/plugins (Go): affected from 1.6.0; fixed in 1.9.0\n- github.com/containernetworking/plugins (Go): affected from 1.6.0; fixed in 1.9.0\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-2025-67499/ (Markdown: https://insights.sbomify.com/CVE-2025-67499/index.md)","id":"CVE-2025-67499","markdown":"https://insights.sbomify.com/CVE-2025-67499/index.md","name":"CVE-2025-67499","record":{"aliases":["CLEANSTART-2026-CX03241","CLEANSTART-2026-GU03381","CLEANSTART-2026-NW65912","CLEANSTART-2026-SJ63169","GHSA-jv3w-x3r3-g6rm","GO-2025-4222","MINI-2fmx-rpvm-r998","MINI-43px-j8h6-764c","MINI-4fjx-mg5q-fc69","MINI-4jr7-6428-4cg5","MINI-62xp-qm44-f22m","MINI-6vgm-8v79-3gc2","MINI-7mpp-p5rw-p66r","MINI-7r22-2x6g-8vgj","MINI-7vp7-5h98-cfjp","MINI-85cc-vr4c-9fc7","MINI-85x2-mc7g-c4w7","MINI-95w3-vrm5-gjfp","MINI-9cc9-gw6m-c4hf","MINI-9mrx-257j-8fg7","MINI-c28q-9658-3m54","MINI-fjf3-69v7-3cxh","MINI-m6cq-2xph-4vhg","MINI-mvmc-r869-5rvr","MINI-q586-4fq7-25fj","MINI-rghw-62c4-6gxq","MINI-wgpc-37gm-5vcf","UBUNTU-CVE-2025-67499","openSUSE-SU-2026:10261-1"],"analysis":{"component_type":"container_or_infrastructure","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"CNI portmap plugin","requires_auth":"low_privilege","summary":"Containers can intercept all traffic destined for a specific port on the host when the nftables backend is used, exposing sensitive data.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"cni_network_plugins","vendor":"linuxfoundation"}],"cvss":{"score":6.6,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:H","version":"3.1"},"cwes":[{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"description":"The CNI portmap plugin allows containers to emulate opening a host port, forwarding that traffic to the container. Versions 1.6.0 through 1.8.0  inadvertently forward all traffic with the same destination port as the host port when the portmap plugin is configured with the nftables backend, thus ignoring the destination IP. This includes traffic not intended for the node itself, i.e. traffic to containers hosted on the node. Containers that request HostPort forwarding can intercept all traffic destined for that port. This requires that the portmap plugin be explicitly configured to use the nftables backend. This issue is fixed in version 1.9.0. To workaround, configure the portmap plugin to use the iptables backend. It does not have this vulnerability.","ecosystems":["Go","openSUSE:Tumbleweed"],"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":"CNI Plugins Portmap nftables backend intercepts non-local traffic","id":"CVE-2025-67499","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"information_disclosure","year":"2025"},"n_packages":4,"n_references":3,"next":{"headline":"Mastodon Error Handling Discrepancy Enables Private Status Existence Enumeration","id":"CVE-2025-67500"},"packages":[{"ecosystem":"Go","fixed":["1.9.0"],"introduced":["1.6.0"],"last_affected":[],"package":"github.com/containernetworking/plugins","purl":null,"source":"GHSA-jv3w-x3r3-g6rm"},{"ecosystem":"Go","fixed":["1.9.0"],"introduced":["1.6.0"],"last_affected":[],"package":"github.com/containernetworking/plugins","purl":"pkg:golang/github.com/containernetworking/plugins","source":"GHSA-jv3w-x3r3-g6rm"},{"ecosystem":"Go","fixed":["1.9.0"],"introduced":["1.6.0"],"last_affected":[],"package":"github.com/containernetworking/plugins","purl":"pkg:golang/github.com/containernetworking/plugins","source":"GO-2025-4222"},{"ecosystem":"openSUSE:Tumbleweed","fixed":["29.2.1_ce-37.1"],"introduced":["0"],"last_affected":[],"package":"docker","purl":"pkg:rpm/opensuse/docker\u0026distro=openSUSE%20Tumbleweed","source":"openSUSE-SU-2026:10261-1"}],"prev":{"headline":"Further research determined the issue is not a vulnerability.","id":"CVE-2025-67498"},"products":["plugins"],"published":"2025-12-09","related":[],"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":"CC BY 4.0","name":"SUSE","prefix":"openSUSE"},{"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":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-12-10","vendors":["containernetworking"]},"summary":"Containers can intercept all traffic destined for a specific port on the host when the nftables backend is used, exposing sensitive data.","url":"https://insights.sbomify.com/CVE-2025-67499/"}
