Authorization bypass via null endpoint path matcher
Published Apr 28, 2025 · Updated May 16, 2025
Authorization bypass in affected Spring Boot releases allows remote attackers to access protected /null routes through HTTP requests. The servlet and reactive EndpointRequest.to() implementations pass a null path mapping into matcher construction, producing a null/** matcher instead of an empty matcher. Exposure requires Spring Security, a disabled or unexposed referenced actuator endpoint, EndpointRequest.to() in the security chain, and an application route at /null that requires protection.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=2.7.x <2.7.25
