Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-72663 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- kibana (Bitnami): affected from 8.0.0; fixed in 8.19.20, 9.4.5\n- elk (Bitnami): affected from 8.0.0; fixed in 8.19.20, 9.4.5\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-2026-72663/ (Markdown: https://insights.sbomify.com/CVE-2026-72663/index.md)","id":"CVE-2026-72663","markdown":"https://insights.sbomify.com/CVE-2026-72663/index.md","name":"CVE-2026-72663","record":{"aliases":["BIT-elk-2026-72663","BIT-kibana-2026-72663","GHSA-pw35-6253-9877","MINI-24pc-7g83-5x82","MINI-676c-p9q5-34hh","MINI-94vc-3g62-rcxg","MINI-jqg6-qv39-8jw5","MINI-qwhh-3fg9-jm7m","MINI-vjpg-5vfh-6jp9","MINI-xhfw-jwc7-5vrh"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Kibana visualization tool","requires_auth":"low_privilege","summary":"Attackers can cause denial of service in Kibana by submitting deeply nested expressions to TSVB visualizations, blocking request processing threads.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"elastic","cpe":[{"product":"kibana","vendor":"elastic"}],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-407","name":"Inefficient Algorithmic Complexity"}],"description":"Inefficient Algorithmic Complexity (CWE-407) in Kibana can lead to denial of service via Input Data Manipulation (CAPEC-153).
