What is CVE-2026-41844?

A vulnerability exists in Spring MVC and Spring WebFlux applications that improperly configures the mapping for the URL pattern '/**'. When the view name isn't explicitly defined, this flaw allows an attacker to craft a malicious link. Consequently, it may lead to a 302 redirect to an arbitrary external host using the 'redirect:' prefix, potentially compromising user trust and application integrity. This issue affects multiple versions of the Spring Framework, exposing users to potential security breaches if not mitigated.

Affected Version(s)

Spring Framework 7.0.0 < 7.0.7.1

Spring Framework 6.2.0 < 6.2.18.1

Spring Framework 6.1.0 < 6.1.28
