3.1 · LOW

Spring MVC and WebFlux applications are vulnerable to cache poisoning when resolving static resources.

Published Apr 29, 2026CWE-524EPSS 0.24%

Overview

CVE-2026-22741 is a low-severity vulnerability. It was published on April 29, 2026 and has a CVSS 3.1 base score of 3.1 (LOW).

This vulnerability has a CVSS 3.1 base score of 3.1, rated LOW. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

Spring MVC and WebFlux applications are vulnerable to cache poisoning 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 configuring the  resource chain support https://docs.spring.io/spring-framework/reference/web/webmvc/mvc-config/static-resources.html#page-title  with caching enabled

* the application adds support for encoded resources resolution

* the resource cache must be empty when the attacker has access to the application

When all the conditions above are met, the attacker can send malicious requests and poison the resource cache with resources using the wrong encoding. This can cause a denial of service by breaking the front-end application for clients.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
