While the specific CVEs and technical details remain undisclosed in this initial advisory, the potential impact is significant. A remote, unauthenticated attacker could exploit these vulnerabilities to achieve a range of malicious outcomes, including denial of service, arbitrary code execution, data manipulation, sensitive information disclosure, and the circumvention of security controls. The vulnerabilities affect Wazuh installations across Linux, Windows, and macOS environments. Due to the broad functionality of Wazuh in security monitoring and incident response, successful exploitation could lead to widespread compromise within targeted organizations.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eThe attacker identifies a vulnerable Wazuh instance accessible over the network.\u003c/li\u003e\n\u003cli\u003eThe attacker exploits a vulnerability to bypass authentication or authorization controls.\u003c/li\u003e\n\u003cli\u003eThe attacker leverages an arbitrary code execution vulnerability to gain remote shell access to the Wazuh server.\u003c/li\u003e\n\u003cli\u003eThe attacker escalates privileges to gain root or SYSTEM level access on the Wazuh server.\u003c/li\u003e\n\u003cli\u003eThe attacker manipulates Wazuh configuration files to disable security alerts or modify monitoring rules.\u003c/li\u003e\n\u003cli\u003eThe attacker injects malicious code into Wazuh agents to compromise endpoints managed by the platform.\u003c/li\u003e\n\u003cli\u003eThe attacker uses the compromised Wazuh infrastructure to exfiltrate sensitive data collected by the platform.\u003c/li\u003e\n\u003cli\u003eThe attacker launches denial-of-service attacks against monitored systems using compromised Wazuh agents.\u003c/li\u003e\n\u003c/ol\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eSuccessful exploitation of these vulnerabilities could have severe consequences. An attacker could gain complete control over the Wazuh platform, disabling security monitoring, manipulating security data, and compromising monitored endpoints. This could lead to undetected data breaches, widespread malware infections, and significant disruption of IT operations. The lack of specific vulnerability information makes it difficult to assess the exact scope of impact, but the wide deployment of Wazuh in security-critical environments means that numerous organizations are potentially at risk.\u003c/p\u003e\n\u003ch2 id=\"recommendation\"\u003eRecommendation\u003c/h2\u003e\n\u003cul\u003e\n\u003cli\u003eMonitor Wazuh server process creation for unusual child processes that might indicate exploitation, using the \u0026ldquo;Wazuh Server Suspicious Process\u0026rdquo; Sigma rule.\u003c/li\u003e\n\u003cli\u003eInspect Wazuh server logs for authentication bypass attempts and unauthorized configuration changes.\u003c/li\u003e\n\u003cli\u003eBlock network connections originating from newly created Wazuh agent processes using the \u0026ldquo;Wazuh Agent Outbound Connection\u0026rdquo; Sigma rule, to prevent lateral movement.\u003c/li\u003e\n\u003c/ul\u003e\n","date_modified":"2026-04-30T09:09:10Z","date_published":"2026-04-30T09:09:10Z","id":"/briefs/2026-05-wazuh-multiple-vulnerabilities/","summary":"Multiple vulnerabilities in Wazuh allow an attacker to perform a denial of service attack, execute arbitrary code, manipulate data, disclose confidential information, or bypass security measures.","title":"Multiple Vulnerabilities in Wazuh Allow for Code Execution and Data Manipulation","url":"https://feed.craftedsignal.io/briefs/2026-05-wazuh-multiple-vulnerabilities/"}],"language":"en","title":"CraftedSignal Threat Feed — Wazuh","version":"https://jsonfeed.org/version/1.1"}
