Starting in version 4.4.0 and prior to version 4.9.1, an unsafe deserialization vulnerability allows for remote code execution on Wazuh servers. DistributedAPI parameters are a serialized as JSON and deserialized using `as_wazuh_object` (in `framework/wazuh/core/cluster/common.py`). If an attacker manages to inject an unsanitized dictionary in DAPI request/response, they can forge an unhandled exception (`__unhandled_exc__`) to evaluate arbitrary python code. The vulnerability can be triggered by anybody with API access (compromised dashboard or Wazuh servers in the cluster) or, in certain configurations, even by a compromised agent. Version 4.9.1 contains a fix.","published":"2025-02-10T20:15:43.000Z","lastModified":"2026-06-17T08:57:54.000Z","status":"Analyzed","sourceIdentifier":"security-advisories@github.com","cvss":{"version":"3.1","score":9.9,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:H/A:H"},"cwe":["CWE-502"],"affected":["wazuh/wazuh"],"epss":{"score":0.9384,"percentile":0.99843,"date":"2026-10-27","history":[]},"kev":{"listed":true,"dateAdded":"2025-06-10","dueDate":"2025-07-01","knownRansomwareCampaignUse":"Unknown","notes":"Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.\nhttps://wazuh.com/blog/addressing-the-cve-2025-24016-vulnerability/ ; https://github.com/wazuh/wazuh/security/advisories/GHSA-hcrc-79hj-m3qh ; https://nvd.nist.gov/vuln/detail/CVE-2025-24016"},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"urgent","text":"Known to be exploited in the wild (CISA KEV, CISA remediation deadline 1 July 2025).
