CVE-2025-41232: 
Java vulnerability analysis and mitigation

CVE-2025-41232 is a security vulnerability discovered in Spring Security Aspects, disclosed on May 19, 2025. The vulnerability affects Spring Security versions 6.4.0 through 6.4.5, where the system may not correctly locate method security annotations on private methods, potentially leading to authorization bypass issues (Spring Security, NVD).

The vulnerability occurs when Spring Security Aspects fails to properly locate and enforce method security annotations on private methods. It has been assigned a CVSS v3.1 base score of 9.1 (Critical) with the vector string CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N, indicating high severity with potential for remote exploitation. The vulnerability is classified under CWE-693 (Protection Mechanism Failure) (Spring Security, Wiz).

The vulnerability enables unauthorized access to protected methods, potentially leading to a security bypass in affected applications. This could result in unauthorized users gaining access to sensitive functionality or data that should be restricted by method-level security controls (Wiz).

The primary mitigation is to upgrade to Spring Security version 6.4.6, which contains the fix for this vulnerability. No other mitigation steps are necessary. Applications that do not use @EnableMethodSecurity(mode=ASPECTJ) or spring-security-aspects, or have no Spring Security-annotated private methods are not affected by this vulnerability (Spring Security, Spring Blog).

The vulnerability was responsibly reported by a security researcher named Vitalii, and Spring Framework developers promptly addressed it by releasing a security advisory and a fixed version. The Spring Security team released version 6.4.6 on May 19, 2025, specifically to address this vulnerability (Spring Security, Spring Blog).
