CVE-2026-92443 · Severity: info · Published 2026-11-10

Kong Gateway Enterprise and Kong AI Gateway contain caching plugins that may serve cached responses across different users based on requests with Authorization or Proxy-Authorization headers. This allows an attacker to obtain responses originally intended for other authenticated users, potentially exposing sensitive data or authentication tokens cached from previous requests.

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).
