A Spring MVC application that uses UrlFileNameViewController that is mapped with an end-of-path, and does not have a configured prefix is vulnerable to an open redirect. Spring Framework 7.0.0 - 7.0.8 Spring Framework 6.2.0 - 6.2.19 Spring Framework 6.1.0 - 6.1.28 Spring Framework 6.0.0 - 6.0.30 Spring Framework 5.3.0 - 5.3.49 Spring Framework 5.2.25.RELEASE and earlier
AnalysisAI
Open redirect in Spring Framework's UrlFileNameViewController exposes users of affected Spring MVC applications to phishing and credential-harvesting attacks across all active Spring Framework release trains (5.2.x through 7.0.x). The flaw allows an unauthenticated attacker to craft a URL that causes the vulnerable application to redirect victims to an arbitrary external domain, exploiting the controller's path-to-view-name resolution when end-of-path mapping is used without a configured prefix. …

Vulnerability AssessmentAI
| Exploitation | Three specific conditions must all be present simultaneously: (1) the Spring MVC application must explicitly use UrlFileNameViewController as a controller - this is a non-default, manually configured component not present in standard Spring Boot or Spring MVC auto-configurations; (2) the controller must be registered with an end-of-path mapping pattern (e.g., a wildcard suffix such as '/**'); and (3) no view-name prefix must be configured on the controller, leaving path resolution open to external domain injection. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 6.1 Medium score reflects the true impact ceiling of open redirect: Scope:Changed (S:C) captures that exploitation affects the victim's browser context rather than the server, and C:L/I:L correctly bounds the impact to phishing and session-hijacking risk rather than server compromise. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Upgrade to a Spring Framework release beyond the affected ranges per the vendor advisory at https://spring.io/security/cve-2026-47887 - exact fixed version numbers must be confirmed directly from that advisory, as they are not specified in currently available intelligence. … Detailed patch versions, workarounds, and compensating controls in full report. |
