CVE-2026-92441 · Severity: info · Published 2026-11-10

Kong Gateway Enterprise and Kong AI Gateway are API gateways that route and manage traffic to backend services. These products can be exploited to inject malicious HTTP headers or smuggle requests to upstream servers by including unescaped carriage return and line feed characters in the X-Forwarded-Prefix header when processing regex-based routes. An attacker can manipulate traffic destined for backend services, potentially bypassing security controls or poisoning responses.

Technologies: [Kong AI Gateway](https://junglewise.ai/threats/technologies/kong-ai-gateway), [Kong Gateway Enterprise](https://junglewise.ai/threats/technologies/gateway-enterprise). Vendors: [Kong](https://junglewise.ai/threats/vendors/kong).

## Technical details

The vulnerability exists in regex-based routes where decoded CR/LF characters from the request path are included in the X-Forwarded-Prefix header passed to upstream servers. This allows HTTP header injection and request smuggling attacks. An attacker can craft a request with encoded CR/LF characters in the path, which are decoded and reflected in the X-Forwarded-Prefix header, enabling the attacker to inject arbitrary headers or splice requests to the upstream service.
