HIGH | JUNE 08, 2026 | CVE-2026-41842
Description
Spring MVC and WebFlux applications are vulnerable to Denial of Service (DoS) attacks when resolving static resources.
More precisely, an application can be vulnerable when all the following are true:
- The application uses Spring MVC or Spring WebFlux.
- The application serves static resources from the file system.
- The application has configured versioned resources support.
When all the conditions above are met, an attacker can send malicious requests that are slow to resolve and that can keep HTTP connections in use, potentially leading to Denial of Service in the application.
