Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-4498 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- kibana (Bitnami): affected from 8.0.0; fixed in 8.19.14, 9.2.8, 9.3.3\n- elk (Bitnami): affected from 8.0.0; fixed in 8.19.14, 9.2.8, 9.3.3\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-2026-4498/ (Markdown: https://insights.sbomify.com/CVE-2026-4498/index.md)","id":"CVE-2026-4498","markdown":"https://insights.sbomify.com/CVE-2026-4498/index.md","name":"CVE-2026-4498","record":{"aliases":["BIT-elk-2026-4498","BIT-kibana-2026-4498","GHSA-4c73-92cw-x6vq","MINI-8prm-rg8h-qqxp","MINI-9v5c-qc6q-rcv8","MINI-hxw3-jp77-7h3q","MINI-pj7w-g632-7qhw","MINI-x3xw-p95g-jxm8","MINI-x625-4cf3-47gj"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["data_read","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Kibana Fleet plugin","requires_auth":"low_privilege","summary":"Authenticated users with Fleet privileges can read index data beyond their Elasticsearch RBAC scope due to unnecessary privilege execution in debug routes.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"elastic","cpe":[{"product":"kibana","vendor":"elastic"}],"cvss":{"score":7.7,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-250","name":"Execution with Unnecessary Privileges"}],"description":"Execution with Unnecessary Privileges (CWE-250) in Kibana’s Fleet plugin debug route handlers can lead reading index data beyond their direct Elasticsearch RBAC scope via Privilege Abuse (CAPEC-122).
