Overview

Affected versions of this package are vulnerable to Out-of-bounds Read in the try_acme_redirect process when the server is started with the --acme-redirect option and a plaintext-TCP listener is exposed. An attacker can obtain sensitive heap memory contents by sending a crafted HTTP GET request, resulting in the disclosure of potentially sensitive information from other clients' requests in the response's Location header. This is only exploitable if the server is configured with --acme-redirect and exposes a plaintext-TCP listener.
