CVE-2026-74038
HighCVSS 7.1Exploitation Probability (EPSS)
Low risk28th percentile - higher than 28% of all known CVEs
Summary
Wazuh 4.0.0 before 4.14.6 contains a path traversal vulnerability that allows unauthenticated remote attackers to cause denial of service by enrolling an agent with a dot-sequence name such as ".." through the enrollment port. Attackers exploit insufficient validation in OS_IsValidName() and unsafe path concatenation in delete_diff() to resolve the traversal to the parent queue directory, causing its subdirectories to be removed and stopping all Wazuh services requiring manual recovery.
Risk Assessment
The risk includes complete shutdown of Wazuh services, which could disrupt security monitoring and require manual intervention.
Recommendation
It is recommended to immediately update Wazuh to version 4.14.6 or later, which includes the fix.
