GHSA-6p4f-wcwh-5vvm: CVE-2026-22745 : Denial of service in static resource handling on Windows platforms
Spring MVC and WebFlux applications are vulnerable to Denial of Service attacks when resolving static resources.
More precisely, an application can be vulnerable when all the following are true:
the application is using Spring MVC or Spring WebFlux the application is serving static resources from the file system the application is running on a Windows platform
When all the conditions above are met, the attacker can send malicious requests that are slow to resolve and that can keep HTTP connections in use. This can cause a Denial of Service on the application.

Frequently Asked Questions
Which deployments are affected?
Affected deployments use Spring MVC or Spring WebFlux, serve static resources from the file system, and run on Windows. All three conditions must be present for the described denial-of-service condition.
Does exploitation require authentication or user interaction?
No. The supplied CVSS vector indicates network-based exploitation with low attack complexity, no privileges required, and no user interaction.
What is the practical impact of a malicious request?
Malicious requests can be slow to resolve and keep HTTP connections in use. This can deny service to the application; no confidentiality or integrity impact is identified in the provided CVSS vector.
