An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2025-9708 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- KubernetesClient (NuGet): affected all versions; fixed in 17.0.14\n- KubernetesClient (NuGet): affected all versions; fixed in 17.0.14\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-2025-9708/ (Markdown: https://insights.sbomify.com/CVE-2025-9708/index.md)","id":"CVE-2025-9708","markdown":"https://insights.sbomify.com/CVE-2025-9708/index.md","name":"CVE-2025-9708","record":{"aliases":["GHSA-w7r3-mgwf-4mqq"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":true,"product_category":"Kubernetes C# Client","requires_auth":"none","summary":"Attackers can intercept Kubernetes API traffic via man-in-the-middle attacks due to improper certificate validation in the C# client's custom CA mode.","user_interaction":"required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"kubernetes","cpe":[],"cvss":{"score":6.8,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-295","name":"Improper Certificate Validation"}],"description":"A vulnerability exists in the Kubernetes C# client where the certificate validation logic accepts properly constructed certificates from any Certificate Authority (CA) without properly verifying the trust chain.
