Information Disclosure in Spring Framework

Detection Guidance

This vulnerability affects Spring MVC and WebFlux applications using certain versions of the Spring Framework with multiple resource handlers and shared caching. Detection involves identifying if your application is running an affected Spring Framework version and if it uses multiple resource handlers with shared caches.

Since the vulnerability is related to the resolution and caching of static resources, there are no specific network or system commands provided to detect exploitation attempts or presence of the vulnerability.

The recommended approach is to verify the Spring Framework version in use and upgrade to the fixed versions as listed in the advisory.

Executive Summary

CVE-2026-41841 is a medium-severity information disclosure vulnerability affecting Spring Framework versions 7.0.0 to 7.0.7, 6.2.0 to 6.2.18, 6.1.0 to 6.1.27, and 5.3.0 to 5.3.48.

The issue occurs in applications using Spring MVC or Spring WebFlux that have multiple resource handlers configured for different locations, where at least one handler requires authentication and a shared cache is used.

An attacker can exploit this vulnerability by accessing a protected resource if a publicly available resource with the same name was resolved first and cached, leading to unauthorized information disclosure.

Impact Analysis

This vulnerability can lead to unauthorized disclosure of protected information in Spring MVC or WebFlux applications.

If an attacker accesses a publicly available resource first and it gets cached, they may then be able to access a protected resource with the same name without proper authentication.

This could expose sensitive data that should be restricted, potentially compromising confidentiality.

Mitigation Strategies

The primary and immediate step to mitigate this vulnerability is to upgrade the Spring Framework to the fixed versions.

• Upgrade to Spring Framework 7.0.8 (OSS) or 7.0.7.1 (Commercial) for 7.0.x versions.
• Upgrade to Spring Framework 6.2.19 (OSS) or 6.2.18.1 (Commercial) for 6.2.x versions.
• Upgrade to Spring Framework 6.1.28 (Commercial) for 6.1.x versions.
• Upgrade to Spring Framework 5.3.49 (Commercial) for 5.3.x versions.

No additional mitigation steps are required beyond upgrading.
