CVE-2026-44256

Description

Wazuh is a free and open source platform used for threat prevention, detection, and response. From 4.4.0 until 4.14.6 and 5.0.0-beta2, api/api/middlewares.py decodes the Basic authentication username before credential validation and passes it to the access logger without neutralizing control characters. api/api/alogging.py interpolates that value into the plain-text API log. An unauthenticated attacker can include carriage returns or line feeds in the username to forge entries, obscure activity, or poison systems that consume the plain-text audit log. The JSON log format is not affected because JSON serialization escapes these characters. This issue is fixed in versions 4.14.6 and 5.0.0-beta2.
