# CVE-2026-17578

## Summary

- **CVE ID:** CVE-2026-17578
- **Severity:** LOW
- **CVSS Score:** 2.3 (CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:L/VI:N/VA:N/SC:L/SI:N/SA:N/AU:N/R:U/U:Amber)
- **CWE:** CWE-323
- **Published:** Aug 5, 2026
- **Last Modified:** Aug 5, 2026

## Description

Kong Event Gateway versions 1.0.0 through 1.1.1 and 1.2.0 do not enforce key rotation before reaching NIST SP 800-38D recommended usage limit for AES-GCM encryption keys with random nonces when the AWS IAM encryption feature is enabled.



If a producer sends messages at a sustained high rate without key rotation, which only occurs on reboot of the Kong Event Gateway instance, the probability of a nonce collision becomes non-negligible. An authorized consumer who detects a nonce collision can recover parts of plaintext from the affected messages.



New versions 1.1.2 and 1.2.1 enforce automatic key rotation before the recommended usage limit is reached.

## Affected Products

- Kong — Kong Event Gateway (1.0.0)
