Spring Framework Flaw Allows Unauthorized Access via Security Bypass - #CVE-2025-41232
A critical vulnerability (CVE-2025-41232) has been discovered in the Spring Framework, affecting its method-level security implementation when using AspectJ. The flaw allows unauthorized access by bypassing security measures on private methods annotated with security annotations. This issue specifically impacts applications utilizing `@EnableMethodSecurity(mode = ASPECTJ)` in conjunction with `spring-security-aspects`. The vulnerability stems from Spring Security's inability to properly process security annotations on private methods, potentially leading to silent authorization bypasses. Importantly, systems not employing these specific configurations or lacking annotated private methods remain unaffected. To address this security concern, developers are strongly advised to upgrade their Spring Framework to version 6.4.6, which resolves the vulnerability without necessitating additional mitigation steps.
