CVE-2026-9561

Name of the Vulnerable Software and Affected Versions Eclipse Kura versions prior to 5.6.2

Description The software trusts the client-supplied X-Forwarded-For HTTP header as the authoritative source of the client IP address in audit log entries. The org.eclipse.kura.web2 (Web Console) and org.eclipse.kura.rest.provider (REST API) components use this header as the primary IP source when initializing audit context. Additionally, org.eclipse.kura.jetty.customizer unconditionally installs Jetty's ForwardedRequestCustomizer on all HTTP/HTTPS connectors, causing HttpServletRequest.getRemoteAddr() to reflect the attacker-controlled header value. An unauthenticated remote attacker can exploit this to bypass IP-based brute-force protections by spoofing the logged IP address to a non-routable value or cause a denial of service against a third party by injecting a victim's IP address to trigger a ban.

Recommendations Update to version 5.6.2 or later.
