An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-79767 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- gardener/gardener (Go): affected from 1.143.0; fixed in 1.143.3\n- gardener/gardener (Go): affected from 1.143.0; fixed in 1.143.3\n- gardener/gardener (Go): affected from 1.144.0; fixed in 1.144.2\n- gardener/gardener (Go): affected from 1.144.0; fixed in 1.144.2\n- github.com/gardener/gardener (Go): affected all versions; no fix listed\n- github.com/gardener/gardener (Go): affected all versions; fixed in 1.142.6\n- github.com/gardener/gardener (Go): affected all versions; fixed in 1.142.6\n- github.com/gardener/gardener (Go): affected all versions; fixed in 1.142.6\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-2026-79767/ (Markdown: https://insights.sbomify.com/CVE-2026-79767/index.md)","id":"CVE-2026-79767","markdown":"https://insights.sbomify.com/CVE-2026-79767/index.md","name":"CVE-2026-79767","record":{"aliases":["GHSA-gfjv-gqf2-c888","GO-2026-6568"],"analysis":{"component_type":"cloud_service","fix_type":"upgrade","impacts":["privilege_escalation","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Kubernetes cluster management","requires_auth":"high_privilege","summary":"A project administrator can bypass authorization checks to add unauthorized group subjects, gaining broad access to sensitive cluster resources and credentials.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":5.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:L/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-863","name":"Incorrect Authorization"}],"description":"Gardener implements the automated management and operation of Kubernetes clusters as a service. Prior to 1.142.6, 1.143.3, 1.144.2, and 1.145.0, the customverbauthorizer admission plugin's mustCheckProjectMembers manage-members check compares changes to User subjects but does not account for Group or ServiceAccount subjects in Project.spec.members. A project administrator who lacks manage-members permission can add arbitrary Group or ServiceAccount subjects, including the system:authenticated Group, and thereby grant broad project access. The resulting access can include Shoots, Secrets, and cloud provider credentials.
