An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-25769 exists.\n\nAffected product: Wazuh Wazuh. 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-2026-25769/ (Markdown: https://insights.sbomify.com/CVE-2026-25769/index.md)","id":"CVE-2026-25769","markdown":"https://insights.sbomify.com/CVE-2026-25769/index.md","name":"CVE-2026-25769","record":{"aliases":["GHSA-3gm7-962f-fxw5"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":true,"product_category":"Wazuh security platform","requires_auth":"high_privilege","summary":"An attacker with access to a worker node can achieve remote code execution with root privileges on the master node via insecure deserialization.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"wazuh","vendor":"wazuh"}],"cvss":{"score":9.1,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-502","name":"Deserialization of Untrusted Data"}],"description":"Wazuh is a free and open source platform used for threat prevention, detection, and response.

All Wazuh deployments using cluster mode (master/worker architecture) and any organization with a compromised worker node (e.g., through initial access, insider threat, or supply chain attack) are impacted. An attacker who gains access to a worker node (through any means) can achieve full RCE on the master node with root privileges.
