Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-78609 in the wild and no public exploit code.\n\nAffected product: Elastic Eck Operator. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2026-78609/ (Markdown: https://insights.sbomify.com/CVE-2026-78609/index.md)","id":"CVE-2026-78609","markdown":"https://insights.sbomify.com/CVE-2026-78609/index.md","name":"CVE-2026-78609","record":{"aliases":["GHSA-h699-694r-9xxf"],"analysis":{"component_type":"container_or_infrastructure","fix_type":"patch","impacts":["data_modify","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Elastic Cloud on Kubernetes","requires_auth":"low_privilege","summary":"Attackers with limited Kubernetes permissions can spoof metadata to inject malicious certificates into Elasticsearch trust bundles, enabling unauthorized data modification.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"elastic","cpe":[{"product":"elastic_cloud_on_kubernetes","vendor":"elastic"}],"cvss":{"score":5.4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-863","name":"Incorrect Authorization"}],"description":"Incorrect Authorization (CWE-863) in Elastic Cloud on Kubernetes (ECK) can lead to unauthorized modification of data via Metadata Spoofing (CAPEC-690).
