CVE-2026-30893Public exploitNetwork attack vector

Code execution via unconfined cluster archive paths

Published Apr 29, 2026 · Updated Apr 29, 2026

Path traversal in Wazuh Manager 4.4.0 through 4.14.3 allows remote authenticated users to write files via cluster synchronization. decompress_files() passes peer-controlled archive paths directly to os.path.join() and opens the result without normalization or a containment check. A valid cluster key is required; writes run with the cluster daemon's privileges and can replace loaded Python modules for code execution.
