Spring Cloud Gateway: Origin Validation Error

Published Updated By the CyberSecBulletin desk

CVE-2026-47825 is a high-severity origin validation error vulnerability in Spring Cloud Gateway from Spring, with a CVSS 3.1 base score of 8.6 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 3.1.13, 4.1.13, 4.2.9 as the first without the flaw, so updating Spring Cloud Gateway to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.18% 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 Spring Cloud Gateway to 3.1.13 or 4.1.13 or 4.2.9 or 4.3.4.1, whichever matches your release line, or a later version.
  2. Read the advisory on spring.io for workarounds and exact fixed builds.
  3. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
