Spring for GraphQL: Exposure of Sensitive Information to an Unauthorized Actor
CVE-2026-59288 is a high-severity exposure of sensitive information to an unauthorized actor vulnerability in Spring for GraphQL from Spring, with a CVSS 3.1 base score of 7.4 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. Affected Spring for GraphQL versions: 2.0.0 through 2.0.4; 1.4.0 through 1.4.6; 1.1.0 through 1.3.9, and others listed below. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.37% 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
- Check which version of Spring for GraphQL you run against the affected versions below, and install the vendor's latest release.
- 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.

Official description
The GraphiQL page bundled with Spring for GraphQL sends requests to the GraphQL endpoints of the application. An attacker can share a malicious URL so that the victim's browser might leak confidential information to the attacker's website. Spring for GraphQL 2.0.0 - 2.0.4 Spring for GraphQL 1.4.0 - 1.4.6 Spring for GraphQL 1.1.0 - 1.3.9 Spring for GraphQL 1.0.0 - 1.0.7

The underlying weakness: Exposure of Sensitive Information to an Unauthorized Actor
The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information.
How developers prevent this class of flaw
- Compartmentalize the system to have safe areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area. Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
