An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-74030 in the wild and no public exploit code.\n\nAffected product: wazuh-agent. 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-2026-74030/ (Markdown: https://insights.sbomify.com/CVE-2026-74030/index.md)","id":"CVE-2026-74030","markdown":"https://insights.sbomify.com/CVE-2026-74030/index.md","name":"CVE-2026-74030","record":{"aliases":["GHSA-x8v7-g49q-ff7j"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Wazuh security platform","requires_auth":"high_privilege","summary":"Attackers controlling the Wazuh manager can exhaust agent memory via malicious YAML policies, causing denial of service on agents.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":6.9,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-776","name":"Improper Restriction of Recursive Entity References in DTDs"}],"description":"Wazuh from 3.9.0 before 4.14.8 contains an uncontrolled YAML alias expansion vulnerability in yaml2json_node that allows a manager-controlled policy to exhaust agent memory.
