An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2019-11253 exists.\n\nAffected packages and fixed versions:\n- k8s.io/kubernetes (Go): affected from 1.0.0; fixed in 1.13.12, 1.14.8, 1.15.5, 1.16.2\n- k8s.io/kubernetes (Go): affected from 1.0.0; fixed in 1.13.12\n- k8s.io/kubernetes (Go): affected from 1.0.0; fixed in 1.13.12\n- k8s.io/kubernetes (Go): affected from 1.14.0; fixed in 1.14.8\n- k8s.io/kubernetes (Go): affected from 1.14.0; fixed in 1.14.8\n- k8s.io/kubernetes (Go): affected from 1.15.0; fixed in 1.15.5\n- k8s.io/kubernetes (Go): affected from 1.15.0; fixed in 1.15.5\n- k8s.io/kubernetes (Go): affected from 1.16.0; fixed in 1.16.2\n- k8s.io/kubernetes (Go): affected from 1.16.0; fixed in 1.16.2\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-2019-11253/ (Markdown: https://insights.sbomify.com/CVE-2019-11253/index.md)","id":"CVE-2019-11253","markdown":"https://insights.sbomify.com/CVE-2019-11253/index.md","name":"CVE-2019-11253","record":{"aliases":["CLEANSTART-2025-ZG19712","DEBIAN-CVE-2019-11253","GHSA-pmqp-h87c-mr78","GO-2022-0703","RHEA-2019:3809","RHSA-2019:3132","RHSA-2020:2799","RHSA-2020:2863","RHSA-2020:2870"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Kubernetes API server","requires_auth":"none","summary":"Authorized users can send malicious YAML or JSON payloads to the Kubernetes API server, causing resource exhaustion and service unavailability.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"kubernetes","cpe":[{"product":"kubernetes","vendor":"kubernetes"},{"product":"openshift_container_platform","vendor":"redhat"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-776","name":"Improper Restriction of Recursive Entity References in DTDs"},{"id":"CWE-20","name":"Improper Input Validation"}],"description":"Improper input validation in the Kubernetes API server in versions v1.0-1.12 and versions prior to v1.13.12, v1.14.8, v1.15.5, and v1.16.2 allows authorized users to send malicious YAML or JSON payloads, causing the API server to consume excessive CPU or memory, potentially crashing and becoming unavailable.
