Miggo AIRoot Cause Analysis

The vulnerability arises from a mismatch in URI normalization between SaToken's AntPathMatcher and Spring's path resolution. SaToken's SaRouter.match() function treats '/admin/password' and '/admin/password/' as distinct paths, while Spring MVC considers them equivalent. This allows attackers to bypass authentication by appending a trailing slash to protected routes. The SaRouter.match() function is directly responsible for defining protected paths but fails to enforce consistent normalization, making it the root cause of the bypass.
