SCA: security update for github.com/go-acme/lego/v4 (GHSA-q82r-2j7m-9rv4)

medium Tenable Self-Hosted Container Security Plugin ID 431692

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Let's Encrypt client and ACME library written in Go (Lego). In versions 4.25.1 and below, the
 github.com/go-acme/lego/v4/acme/api package (thus the lego library and the lego cli as well) don't enforce
 HTTPS when talking to CAs as an ACME client. Unlike the http-01 challenge which solves an ACME challenge
 over unencrypted HTTP, the ACME protocol requires HTTPS when a client communicates with the CA to performs
 ACME functions. However, the library fails to enforce HTTPS both in the original discover URL (configured
 by the library user) and in the subsequent addresses returned by the CAs in the directory and order
 objects. If users input HTTP URLs or CAs misconfigure endpoints, protocol operations occur over HTTP
 instead of HTTPS. This compromises privacy by exposing request/response details like account and request
 identifiers to network attackers. This was fixed in version 4.25.2. (CVE-2025-54799)
