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-2020-8565 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- k8s.io/kubernetes (Go): affected all versions; fixed in 1.20.0-alpha.2\n- k8s.io/kubernetes (Go): affected all versions; fixed in 1.20.0-alpha.2\n- k8s.io/client-go (Go): affected all versions; fixed in 0.17.16\n- k8s.io/client-go (Go): affected all versions; fixed in 0.17.16\n- k8s.io/client-go (Go): affected all versions; fixed in 0.20.0-alpha.2\n- k8s.io/client-go (Go): affected from 0.18.0; fixed in 0.18.14\n- k8s.io/client-go (Go): affected from 0.18.0; fixed in 0.18.14\n- k8s.io/client-go (Go): affected from 0.19.0; fixed in 0.19.6\n- k8s.io/client-go (Go): affected from 0.19.0; fixed in 0.19.6\n- k8s.io/client-go (Go): affected from 0.20.0-alpha.0; fixed in 0.20.0-alpha.2\n- k8s.io/client-go (Go): affected from 0.20.0-alpha.0; fixed in 0.20.0-alpha.2\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-2020-8565/ (Markdown: https://insights.sbomify.com/CVE-2020-8565/index.md)","id":"CVE-2020-8565","markdown":"https://insights.sbomify.com/CVE-2020-8565/index.md","name":"CVE-2020-8565","record":{"aliases":["AZL-41878","CLEANSTART-2025-JF58630","CLEANSTART-2026-AY16638","DEBIAN-CVE-2020-8565","GHSA-8cfg-vx93-jvxw","GO-2021-0064"],"analysis":{"component_type":"container_or_infrastructure","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Kubernetes","requires_auth":"low_privilege","summary":"Attackers with log access can steal authorization tokens if Kubernetes logging is set to level 9 or higher.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"kubernetes","cpe":[{"product":"kubernetes","vendor":"kubernetes"}],"cvss":{"score":4.7,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-532","name":"Insertion of Sensitive Information into Log File"}],"description":"In Kubernetes, if the logging level is set to at least 9, authorization and bearer tokens will be written to log files.
