How to fix?

Upgrade to version 0.15.1, 0.14.8 or higher.

Overview is an identity-aware proxy that enables secure access to internal applications.

Affected versions of this package are vulnerable to Access Restriction Bypass. Envoy, which Pomerium is based on, contains two authorization-related vulnerabilities CVE-2021-32777 and CVE-2021-32779. This may lead to incorrect routing or authorization policy decisions. With specially crafted requests, incorrect authorization or routing decisions may be made by Pomerium.

This issue can only be triggered when using path prefix based policy. Removing any such policies should provide mitigation.
