NewCVE-2026-41842 (opens in a new tab)How to fix?
Upgrade org.springframework:spring-webflux to version 6.0.0, 6.2.19, 7.0.8 or higher.
Overview
org.springframework:spring-webflux is a Spring Framework module that contains support for reactive HTTP and WebSocket clients as well as for reactive server web applications including REST, HTML browser, and WebSocket style interactions.
Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling via static resource resolution when versioned resource support is enabled. An attacker can cause denial of service by sending crafted requests that trigger expensive resource resolution operations against filesystem-backed static resources. Repeated requests can consume server resources and keep HTTP connections occupied for extended periods, potentially degrading performance or rendering the application unavailable.
Note: This is only exploitable if the application uses Spring MVC or Spring WebFlux, serves static resources from the filesystem, and has versioned resource support enabled.
