It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-0528 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/elastic/beats/v7 (Go): affected all versions; fixed in 7.0.0-alpha2.0.20251217054608-6e42552a23ce\n- github.com/elastic/beats/v7 (Go): affected all versions; fixed in 7.0.0-alpha2.0.20251217054608-6e42552a23ce\n- github.com/elastic/beats/v7 (Go): affected all versions; fixed in 7.0.0-alpha2.0.20251217054608-6e42552a23ce\n- github.com/elastic/beats/v7 (Go): affected from 8.0.0; fixed in 8.19.10\n- github.com/elastic/beats/v7 (Go): affected from 8.0.0; fixed in 8.19.10\n- github.com/elastic/beats/v7 (Go): affected from 9.0.0; fixed in 9.1.10\n- github.com/elastic/beats/v7 (Go): affected from 9.0.0; fixed in 9.1.10\n- github.com/elastic/beats/v7 (Go): affected from 9.2.0; fixed in 9.2.4\n- github.com/elastic/beats/v7 (Go): affected from 9.2.0; fixed in 9.2.4\n- github.com/elastic/beats (Go): affected all versions; no fix listed\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-2026-0528/ (Markdown: https://insights.sbomify.com/CVE-2026-0528/index.md)","id":"CVE-2026-0528","markdown":"https://insights.sbomify.com/CVE-2026-0528/index.md","name":"CVE-2026-0528","record":{"aliases":["GHSA-w2gr-585j-r428","GO-2026-4360","MINI-3fhh-fv2x-8hqc","MINI-3hj8-2mr2-v9c8","MINI-3hw6-5m2v-vj79","MINI-4vg4-gj77-x8mj","MINI-8fxr-wvc2-xj9w","MINI-8x5m-8cxm-xf37","MINI-93qx-c8jf-c3w4","MINI-9gg7-7734-rwxw","MINI-gcmp-gvwg-37vc","MINI-h8j2-f6r9-35qq","MINI-j5hf-6x69-ch32","MINI-jhm2-xf77-x329","MINI-jw24-7r3m-x6w2","MINI-pv54-65gv-qvc9","MINI-vvj6-fr95-w8h9","MINI-x88q-qpf7-w8hv"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Elastic Metricbeat","requires_auth":"none","summary":"Attackers can cause denial of service in Elastic Metricbeat by sending malformed payloads to Graphite, Zookeeper, or Prometheus metricsets.","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:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-129","name":"Improper Validation of Array Index"}],"description":"Improper Validation of Array Index (CWE-129) exists in Metricbeat can allow an attacker to cause a Denial of Service through Input Data Manipulation (CAPEC-153) via specially crafted, malformed payloads sent to the Graphite server metricset or Zookeeper server metricset.
