Kong Gateway Enterprise: Use of Cache Containing Sensitive Information

Published Updated By the CyberSecBulletin desk

CVE-2026-92545 is a high-severity use of cache containing sensitive information vulnerability in Kong Gateway Enterprise from Kong, with a CVSS 4.0 base score of 8.7 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists versions 3.10.0.20, 3.13.0.12, 3.14.0.17 as the first without the flaw, so updating Kong Gateway Enterprise to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.36% chance of exploitation within 30 days, which is low compared with other CVEs.

Next patch cycle

High severity with no evidence of exploitation so far.

What to do

  1. Update Kong Gateway Enterprise to 3.10.0.20 or 3.13.0.12 or 3.14.0.17 or 3.15.0.7, whichever matches your release line, or a later version.
  2. Update Kong AI Gateway to 2.2.1 or a later version.
  3. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description

The proxy-cache and proxy-cache-advanced plugins in Kong Gateway Enterprise and Kong AI Gateway omit the request hostname from the cache key which may allow a response cached for a hostname to be served for another.

The underlying weakness: Use of Cache Containing Sensitive Information

The code uses a cache that contains sensitive information, but the cache can be read by an actor outside of the intended control sphere.

How developers prevent this class of flaw

  • Do not store unnecessarily sensitive information in the cache.
