An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2023-5528 exists.\n\nAffected packages and fixed versions:\n- k8s.io/kubernetes (Go): affected all versions; fixed in 1.25.16, 1.26.11, 1.27.8, 1.28.4\n- k8s.io/kubernetes (Go): affected all versions; fixed in 1.25.16\n- k8s.io/kubernetes (Go): affected all versions; fixed in 1.25.16\n- k8s.io/kubernetes (Go): affected from 1.26.0; fixed in 1.26.11\n- k8s.io/kubernetes (Go): affected from 1.26.0; fixed in 1.26.11\n- k8s.io/kubernetes (Go): affected from 1.27.0; fixed in 1.27.8\n- k8s.io/kubernetes (Go): affected from 1.27.0; fixed in 1.27.8\n- k8s.io/kubernetes (Go): affected from 1.28.0; fixed in 1.28.4\n- k8s.io/kubernetes (Go): affected from 1.28.0; fixed in 1.28.4\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-2023-5528/ (Markdown: https://insights.sbomify.com/CVE-2023-5528/index.md)","id":"CVE-2023-5528","markdown":"https://insights.sbomify.com/CVE-2023-5528/index.md","name":"CVE-2023-5528","record":{"aliases":["AZL-32005","AZL-34894","CLEANSTART-2026-EF04271","CLEANSTART-2026-JR27860","GHSA-hq6q-c2x6-hmch","GO-2023-2341"],"analysis":{"component_type":"container_or_infrastructure","fix_type":"patch","impacts":["privilege_escalation"],"network_reachable":"yes","non_default_config":true,"product_category":"Kubernetes Windows nodes","requires_auth":"high_privilege","summary":"Attackers with pod creation rights on Windows nodes using in-tree storage plugins can escalate to admin privileges.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"kubernetes","cpe":[{"product":"fedora","vendor":"fedoraproject"},{"product":"kubernetes","vendor":"kubernetes"}],"cvss":{"score":7.2,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"A security issue was discovered in Kubernetes where a user that can create pods and persistent volumes on Windows nodes may be able to escalate to admin privileges on those nodes.
