Echo: cpp-httplib: security update to 0.18.7-1+e2

medium Tenable Self-Hosted Container Security Plugin ID 463440

Description

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

 - cpp-httplib is a C++11 single-file header-only cross platform HTTP/HTTPS library. Prior to 0.27.0, a
 vulnerability allows attacker-controlled HTTP headers to influence server-visible metadata, logging, and
 authorization decisions. An attacker can supply X-Forwarded-For or X-Real-IP headers which get accepted
 unconditionally by get_client_ip() in docker/main.cc, causing access and error logs (nginx_access_logger /
 nginx_error_logger) to record spoofed client IPs (log poisoning / audit evasion). This vulnerability is
 fixed in 0.27.0. (CVE-2025-66577)

Solution

Update the cpp-httplib library and its related packages to version 0.18.7-1+e2 or later.
