Background
Apache Shiro is a powerful and easy-to-use Java security framework that provides authentication, authorization, cryptography, and session management capabilities. It is widely used in Java applications to secure sensitive resources and protect against unauthorized access. However, a vulnerability has been discovered in Apache Shiro before version 1.9.1 that could allow an attacker to bypass authorization controls. This vulnerability affects the 'org.apache.shiro:shiro-core' package in the Maven ecosystem.
Vulnerability Detail
The vulnerability, identified as CVE-2022-32532, stems from a misconfiguration in the RegexRequestMatcher of Apache Shiro.
