Source description

As published by the source; long descriptions are shortened.

Spring for GraphQL applications that have enabled the WebSocket transport are vulnerable to Cross-Site WebSocket Hijacking. An attacker can trick an authenticated user into visiting a malicious page, allowing the attacker to execute arbitrary GraphQL operations with the victim's credentials. Affected versions: Spring for GraphQL 2.0.0 through 2.0.3; 1.4.0 through 1.4.5; 1.3.0 through 1.3.8; 1.0.0 through 1.0.6.

# Patch Next advisory brief: CVE-2026-41700

Advisory: Spring for GraphQL: Cross-Site WebSocket Hijacking
IDs: CVE-2026-41700, GHSA-m39w-hqxx-3r48
Record: https://patchnext.com/advisories/cve-2026-41700 (revision 1, source checked 26 Oct 2026, 16:55 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 8.1)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Partial vendor fix; fixed versions by package: org.springframework.graphql:spring-graphql 2.0.4, 1.4.6. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven org.springframework.graphql:spring-graphql: affected >= 2.0.0, <= 2.0.3; >= 1.4.0, <= 1.4.5; >= 1.3.0, <= 1.3.8; >= 1.0.0, <= 1.0.6; fixed in 1.4.6, 2.0.4

## Suggested inspection (read-only)
- Maven org.springframework.graphql:spring-graphql: check the installed version with your package manager.

## Supported action
No complete vendor fix is recorded. Follow the primary source's mitigation guidance and check this record again before closing anything.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on org.springframework.graphql:spring-graphql.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.
