What is CVE-2019-12452?

The Traefik API in versions 1.7.x up to 1.7.11 contains a significant security issue. When the --api flag is enabled and the API is publicly accessible, insufficient access controls allow remote authenticated users to retrieve sensitive information from the API's JSON responses. Specifically, users can uncover password hashes and keys from the Basic and Digest HTTP Authentication sections, as well as from the ClientTLS section. This exposure contradicts the API's documentation and poses serious risks to underlying systems.
