An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-46599 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/k3s-io/k3s (Go): affected all versions; no fix listed\n- github.com/k3s-io/k3s (Go): affected from 1.32.0-rc1; fixed in 1.32.4-rc1\n- github.com/k3s-io/k3s (Go): affected from 1.32.0-rc1; fixed in 1.32.4-rc1\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-2025-46599/ (Markdown: https://insights.sbomify.com/CVE-2025-46599/index.md)","id":"CVE-2025-46599","markdown":"https://insights.sbomify.com/CVE-2025-46599/index.md","name":"CVE-2025-46599","record":{"aliases":["GHSA-864f-7xjm-2jp2","GO-2025-3646"],"analysis":{"component_type":"container_or_infrastructure","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"K3s Kubernetes distribution","requires_auth":"none","summary":"Unauthenticated access to the kubelet ReadOnlyPort in K3s exposes credentials, requiring an upgrade to secure the configuration.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[],"cvss":{"score":6.8,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-1188","name":"Initialization of a Resource with an Insecure Default"}],"description":"CNCF K3s 1.32 before 1.32.4-rc1+k3s1 has a Kubernetes kubelet configuration change with the unintended consequence that, in some situations, ReadOnlyPort is set to 10255.
