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-2026-25770 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-2026-25770/ (Markdown: https://insights.sbomify.com/CVE-2026-25770/index.md)","id":"CVE-2026-25770","markdown":"https://insights.sbomify.com/CVE-2026-25770/index.md","name":"CVE-2026-25770","record":{"aliases":["GHSA-r4f7-v3p6-79jm"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Wazuh security platform","requires_auth":"high_privilege","summary":"Authenticated attackers can escalate privileges to root by overwriting configuration files via the cluster protocol, enabling remote code execution.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"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-732","name":"Incorrect Permission Assignment for Critical Resource"},{"id":"CWE-269","name":"Improper Privilege Management"},{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"Wazuh is a free and open source platform used for threat prevention, detection, and response. Starting in version 3.9.0 and prior to version 4.14.3, a privilege escalation vulnerability exists in the Wazuh Manager's cluster synchronization protocol. The `wazuh-clusterd` service allows authenticated nodes to write arbitrary files to the manager’s file system with the permissions of the `wazuh` system user. Due to insecure default permissions, the `wazuh` user has write access to the manager's main configuration file (`/var/ossec/etc/ossec.conf`). By leveraging the cluster protocol to overwrite `ossec.conf`, an attacker can inject a malicious `\u003clocalfile\u003e` command block. The `wazuh-logcollector` service, which runs as root, parses this configuration and executes the injected command. This chain allows an attacker with cluster credentials to gain full Root Remote Code Execution, violating the principle of least privilege and bypassing the intended security model. Version 4.14.3 fixes the issue.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":false,"headline":"Wazuh has Privilege Escalation to Root via Cluster Protocol File Write","id":"CVE-2026-25770","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"wazuh:wazuh","products":["wazuh:wazuh"],"type":"privilege_escalation","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Wazuh Vulnerable to Denial of Service via Synchronous I/O Blocking in Asynchronous Authentication Middleware","id":"CVE-2026-25771"},"packages":[],"prev":{"headline":"Wazuh Cluster vulnerable to Remote Code Execution via Insecure Deserialization","id":"CVE-2026-25769"},"products":["wazuh"],"published":"2026-03-17","related":[{"cvss_score":9.9,"headline":"Wazuh Server Deserialization of Untrusted Data","id":"CVE-2025-24016","kev_date_added":"2025-06-10","published":"2025-02-10"},{"cvss_score":9.8,"headline":"Wazuh Analysis Engine Event Decoder Heap-based Buffer Overflow Remote Code Execution Vulnerability","id":"CVE-2024-32038","kev_date_added":null,"published":"2024-04-19"},{"cvss_score":9.8,"headline":"Command injection in n/a","id":"CVE-2021-44079","kev_date_added":null,"published":"2021-11-22"},{"cvss_score":9.5,"headline":"Remote code execution and local privilege escalation in Wazuh Windows agent via NetNTLMv2 hash theft","id":"CVE-2024-1243","kev_date_added":null,"published":"2025-06-11"},{"cvss_score":9.1,"headline":"Wazuh cluster worker file sync allows arbitrary file write under /var/ossec (incomplete fix for CVE-2026-30893)","id":"CVE-2026-61800","kev_date_added":null,"published":"2026-08-27"},{"cvss_score":9.1,"headline":"Wazuh: merged-file header path traversal in cluster sync allows arbitrary file write under WAZUH_PATH in Wazuh manager","id":"CVE-2026-48024","kev_date_added":null,"published":"2026-08-19"},{"cvss_score":9.1,"headline":"Path traversal in wazuh","id":"CVE-2026-48162","kev_date_added":null,"published":"2026-08-19"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-03-18","vendors":["wazuh"]},"summary":"Authenticated attackers can escalate privileges to root by overwriting configuration files via the cluster protocol, enabling remote code execution.","url":"https://insights.sbomify.com/CVE-2026-25770/"}
