How to fix?

Upgrade github.com/hashicorp/consul/agent/xds to version 1.20.1 or higher.

Overview

github.com/hashicorp/consul/agent/xds is a provides an implementation of a gRPC service that exports Envoy's xDS API for config discovery. Specifically we support the Aggregated Discovery Service (ADS) only as we control all config.

Affected versions of this package are vulnerable to Path Traversal due to a lack of path normalization, when using URL paths in L7 traffic intentions. An attacker could bypass HTTP request path-based access rules, using URL-encoded paths and/or multiple slashes.
