# Kong AI Gateway: caching plugin may serve one caller's response to another

Link for people: https://infrastack.ai/live/CVE-2026-92443 (this .md is for agents)

The caching plugins in Kong Gateway Enterprise and Kong AI Gateway can return a cached response built for one request carrying an Authorization or Proxy-Authorization header to a different caller. An attacker can receive another user's cached response, which may contain that user's data.

_Summary, check and fix written by a model from the sources; labelled as such._

## Affected

- vendor:kong-gateway-enterprise affected unknown lower bound, before 3.16.0.2 / 3.15.0.7 / 3.14.0.17 / 3.10.0.20 fixed 3.16.0.2, 3.15.0.7, 3.14.0.17, 3.10.0.20

## How to check

Run the Admin API request GET /plugins and look for proxy-cache, proxy-cache-advanced, graphql-proxy-cache-advanced or ai-semantic-cache on any route, service or globally. Compare your Kong Gateway Enterprise version (kong version) with the fixed versions. Affected only if a cache plugin is on a route that serves requests with Authorization or Proxy-Authorization headers.

## Fix

Upgrade Kong Gateway Enterprise to 3.16.0.2, 3.15.0.7, 3.14.0.17 or 3.10.0.20 (all released 2026-11-10). 3.13.0.12 fixes ai-semantic-cache only; its proxy-cache changelog does not list this CVE. Affected plugins: proxy-cache, proxy-cache-advanced, graphql-proxy-cache-advanced, ai-semantic-cache.
