Overview
Affected versions of this package are vulnerable to Incorrect Authorization via route rule matching in normalizeRouteRulePath, where route rules are compared against request paths without first percent-decoding either the rule key or the lookup path. An attacker can bypass route-level protections (such as authentication guards, redirects, or access controls) by requesting a URL with percent-encoded characters that correspond to a protected path, causing the rule to go unmatched at runtime.
