CVE-2026-41856Network attack vector

Unauthorized data access via missed inherited annotations

Published Jun 11, 2026 · Updated Jun 11, 2026

Improper access control in Spring for GraphQL allows remote attackers to read protected GraphQL data through unsecured data fetchers. HandlerMethod uses ResolvableType.resolve() when matching bridged generic methods; failed matches prevent annotations on generic interface methods from being discovered. Exploitation requires Spring Security, enabled method security, and @Controller data fetchers implemented through type hierarchies, after which affected security annotations are ignored.
