Upgrade com.linecorp.armeria:armeria to version 1.43.0 or higher.
Overview
com.linecorp.armeria:armeria is an asynchronous HTTP/2 RPC/REST client/server library built on top of Java 8, Netty, Thrift and gRPC (armeria)
Affected versions of this package are vulnerable to Use of Non-Canonical URL Paths for Authorization Decisions via server request-target validation in DefaultRequestTarget.slowForServer(). An unauthenticated remote attacker can send a request with a . path segment, such as /./admin/secret or /%2e/admin/secret, to skip a path-scoped decorator while FileService, Tomcat, or Jetty resolves the path to the protected resource. Servers using these services behind path-scoped authorization decorators can expose protected files or content.
