Spring for GraphQL: Origin Validation Error
CVE-2026-41700 is a high-severity origin validation error vulnerability in Spring for GraphQL from Spring, with a CVSS 3.1 base score of 8.1 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, but only if a user takes part, for example by opening a link or file. The record lists versions 2.0.3.1, 1.4.5.1, 1.3.9 as the first without the flaw, so updating Spring for GraphQL to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.19% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update Spring for GraphQL to 2.0.3.1 or 1.4.5.1 or 1.3.9 or 1.0.7, whichever matches your release line, or a later version.
- Read the advisory on spring.io for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
- Because the attack needs a user to take part, warn users about unexpected links and files related to this product until it is patched.
