UrlHandlerFilter can be vulnerable to an open redirect when configured with very broadly matching patterns. The issue applies to the filter variants in both Spring MVC and Spring WebFlux. Spring Framework 7.0.0 - 7.0.8 Spring Framework 6.2.0 - 6.2.19
AnalysisAI
Open redirect in Spring Framework's UrlHandlerFilter allows unauthenticated remote attackers to silently redirect authenticated users to attacker-controlled URLs. Affected are Spring Framework 7.0.0-7.0.8 and 6.2.0-6.2.19 in both Spring MVC and Spring WebFlux deployments where UrlHandlerFilter is configured with broadly matching URL patterns. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires that the target application explicitly deploys UrlHandlerFilter (Spring MVC's or Spring WebFlux's variant) and configures it with broadly matching URL patterns - this is not the Spring Framework default out-of-the-box configuration; the filter must be intentionally wired and given permissive patterns by the application developer. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The NVD CVSS base score of 6.1 (Medium) with vector AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N accurately characterizes the attack profile: network-reachable, low complexity, no privileges, but requiring a victim to click a crafted link. … 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 Spring Framework to the first release beyond the affected ranges: for the 7.0.x line, upgrade beyond 7.0.8; for the 6.2.x line, upgrade beyond 6.2.19. … Detailed patch versions, workarounds, and compensating controls in full report. |
