This low-severity CVE scores 3.1 under NVD CVSS v3. EPSS exploit probability: 0.1%, top 76% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

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.
