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-2026-52724 in the wild and no public exploit code.\n\nAffected product: kumahq kuma. 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-2026-52724/ (Markdown: https://insights.sbomify.com/CVE-2026-52724/index.md)","id":"CVE-2026-52724","markdown":"https://insights.sbomify.com/CVE-2026-52724/index.md","name":"CVE-2026-52724","record":{"aliases":[],"analysis":{"component_type":"cloud_service","fix_type":"upgrade","impacts":["account_takeover","code_execution"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Kuma service mesh","requires_auth":"none","summary":"Attackers can intercept dataplane tokens and inject malicious configurations in Kuma Universal mode when TLS verification is disabled by missing CA settings.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","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":"Kuma is a modern Envoy-based service mesh that can run on every cloud across both Kubernetes and VMs. Prior to 2.7.26, 2.9.16, 2.11.14, 2.12.11, and 2.13.7, Universal mode kuma-dp connections to an HTTPS control plane disable TLS peer verification when --ca-cert-file is not supplied and KUMA_CONTROL_PLANE_CA_CERT is unset. The dataplane authentication token is sent over the unverified connection, allowing an on-path attacker to intercept the token, impersonate the control plane, inject a forged bootstrap configuration, and take over the proxy. Standard Kubernetes installations created by kumactl install control-plane or the official Helm chart are unaffected because the mutating admission webhook injects KUMA_CONTROL_PLANE_CA_CERT into each sidecar.
