An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-61800 in the wild and no public exploit code.\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-2026-61800/ (Markdown: https://insights.sbomify.com/CVE-2026-61800/index.md)","id":"CVE-2026-61800","markdown":"https://insights.sbomify.com/CVE-2026-61800/index.md","name":"CVE-2026-61800","record":{"aliases":["GHSA-3jff-488g-335f"],"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":"An attacker with the cluster key can write arbitrary files under /var/ossec on worker nodes, leading to remote code execution as root.","user_interaction":"not_required","vuln_class":"path_traversal"},"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-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"Wazuh is an open-source security platform providing unified XDR and SIEM protection for endpoints and cloud workloads. In versions 4.4.0 through 4.14.6, a party holding the cluster key can write, overwrite, or delete arbitrary files under /var/ossec on worker nodes, leading to remote code execution as root. During cluster file synchronization, the non-merged branch of update_master_files_in_worker() moves each staged file to a destination derived only from safe_join(), which confines the path to /var/ossec but never verifies that the file lands in the directory declared by its cluster_item_key. Because the destination check present on the primary node and on the worker's merged branch was not applied, a peer can place files at attacker-chosen locations under /var/ossec, including paths that are executed as root, and the delete branch has the same gap. This is an incomplete fix for CVE-2026-30893, which addressed traversal outside /var/ossec but left this path able to redirect files anywhere within it. This issue is fixed in version 4.14.7.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Wazuh cluster worker file sync allows arbitrary file write under /var/ossec (incomplete fix for CVE-2026-30893)","id":"CVE-2026-61800","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"wazuh:wazuh","products":["wazuh:wazuh"],"type":"path_traversal","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"github.com/moby/sys/user has a possible DoS via unbounded parsing of user and group database files","id":"CVE-2026-61801"},"packages":[],"prev":{"headline":"Capsule: hostnameRegexHandler.OnUpdate validates stale (old) Tenant regex, allowing invalid AllowedHostnames regex to bypass webhook validation","id":"CVE-2026-61795"},"products":["wazuh"],"published":"2026-08-27","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: 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":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-08-28","vendors":["wazuh"]},"summary":"An attacker with the cluster key can write arbitrary files under /var/ossec on worker nodes, leading to remote code execution as root.","url":"https://insights.sbomify.com/CVE-2026-61800/"}
