Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2019-11243 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- k8s.io/kubernetes (Go): affected from 1.12.0; fixed in 1.12.5, 1.13.1\n- k8s.io/kubernetes (Go): affected from 1.12.0; fixed in 1.12.5\n- k8s.io/kubernetes (Go): affected from 1.12.0; fixed in 1.12.5\n- k8s.io/kubernetes (Go): affected from 1.13.0; fixed in 1.13.1\n- k8s.io/kubernetes (Go): affected from 1.13.0; fixed in 1.13.1\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-2019-11243/ (Markdown: https://insights.sbomify.com/CVE-2019-11243/index.md)","id":"CVE-2019-11243","markdown":"https://insights.sbomify.com/CVE-2019-11243/index.md","name":"CVE-2019-11243","record":{"aliases":["GHSA-gc2p-g4fg-29vh","GO-2025-3645"],"analysis":{"component_type":"container_or_infrastructure","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Kubernetes","requires_auth":"low_privilege","summary":"Kubernetes failed to clear service account credentials in anonymous client configs, potentially exposing sensitive authentication data to unauthorized users.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"kubernetes","cpe":[{"product":"kubernetes","vendor":"kubernetes"},{"product":"trident","vendor":"netapp"}],"cvss":{"score":3.1,"severity":"low","source":"cna","vector":"CVSS:3.0/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:N/A:N","version":"3.0"},"cwes":[{"id":"CWE-212","name":"Improper Removal of Sensitive Information Before Storage or Transfer"},{"id":"CWE-271","name":"Privilege Dropping / Lowering Errors"}],"description":"In Kubernetes v1.12.0-v1.12.4 and v1.13.0, the rest.AnonymousClientConfig() method returns a copy of the provided config, with credentials removed (bearer token, username/password, and client certificate/key data).
