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-2026-18679 in the wild and no public exploit code.\n\nAffected product: Kong Mesh. 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-2026-18679/ (Markdown: https://insights.sbomify.com/CVE-2026-18679/index.md)","id":"CVE-2026-18679","markdown":"https://insights.sbomify.com/CVE-2026-18679/index.md","name":"CVE-2026-18679","record":{"aliases":["GHSA-wc82-hqx6-g35q"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["account_takeover","code_execution"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Kong Mesh service mesh","requires_auth":"none","summary":"An on-path attacker can intercept authentication tokens and impersonate the control plane to inject forged configurations when TLS verification is disabled.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Kong","cpe":[],"cvss":{"score":5.8,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:A/AC:H/AT:P/PR:N/UI:N/VC:N/VI:N/VA:N/SC:H/SI:H/SA:H","version":"4.0"},"cwes":[{"id":"CWE-295","name":"Improper Certificate Validation"}],"description":"When kuma-dp is started against an HTTPS control plane and the operator did not pass a CA certificate, the data plane connects with TLS peer verification disabled, and the dataplane authentication token is sent over that unverified connection.\n\nAn on-path actor can intercept the dataplane authentication token and impersonate the control plane to the data plane, injecting a forged bootstrap configuration and taking over the proxy.","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":"Kong Mesh: kuma-dp connects to the control plane without verifying the TLS certificate when no CA is configured","id":"CVE-2026-18679","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"security_feature_bypass","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"This Power System Buffer Overflow","id":"CVE-2026-18681"},"packages":[],"prev":{"headline":"Kong Mesh: kumactl connects to the control plane without verifying the TLS certificate when no CA is configured","id":"CVE-2026-18678"},"products":["Kong Mesh"],"published":"2026-08-12","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":"2026-08-13","vendors":["Kong Inc."]},"summary":"An on-path attacker can intercept authentication tokens and impersonate the control plane to inject forged configurations when TLS verification is disabled.","url":"https://insights.sbomify.com/CVE-2026-18679/"}
