Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-0543 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- kibana (Bitnami): affected all versions; fixed in 8.19.10, 9.1.10, 9.2.4\n- elk (Bitnami): affected all versions; fixed in 8.19.10, 9.1.10, 9.2.4\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-2026-0543/ (Markdown: https://insights.sbomify.com/CVE-2026-0543/index.md)","id":"CVE-2026-0543","markdown":"https://insights.sbomify.com/CVE-2026-0543/index.md","name":"CVE-2026-0543","record":{"aliases":["BIT-elk-2026-0543","BIT-kibana-2026-0543","GHSA-p2g6-3qpg-4v6h","MINI-2hhm-v6gh-r5rf","MINI-4pq5-mh2f-835c","MINI-7r6g-459q-r99x","MINI-vxrm-526h-j5pg","MINI-wvmx-rcv6-2gq2","MINI-xf4f-48pv-gr58"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Kibana data visualization","requires_auth":"low_privilege","summary":"Authenticated attackers can cause complete service unavailability in Kibana by exploiting improper input validation in the Email Connector.","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-770","name":"Allocation of Resources Without Limits or Throttling"},{"id":"CWE-20","name":"Improper Input Validation"}],"description":"Improper Input Validation (CWE-20) in Kibana's Email Connector can allow an attacker to cause an Excessive Allocation (CAPEC-130) through a specially crafted email address parameter.
