CVE-2026-92545 · Severity: info · Published 2026-11-10

Kong Gateway Enterprise and Kong AI Gateway are API management platforms that cache API responses to improve performance. The proxy-cache and proxy-cache-advanced plugins fail to include the request hostname in the cache key, allowing cached responses intended for one hostname to be served to another. This can result in users receiving incorrect API responses or sensitive data leaking across different API endpoints.

## Technical details

The proxy-cache and proxy-cache-advanced plugins in Kong Gateway Enterprise and Kong AI Gateway omit the request hostname from the cache key calculation, causing cache collisions across different hostnames. An attacker can exploit this by making requests to different hostnames and receiving cached responses intended for other hostnames, leading to information disclosure. The vulnerability affects caching logic where hostname-specific responses should be isolated.
