The update for cpp-httplib fixes these vulnerabilities.

Description
This security update for cpp-httplib addresses critical vulnerabilities involving IP spoofing, log poisoning, and authorization bypass. These issues arise from the acceptance and parsing of client-controlled injected HTTP headers, including unconditional acceptance of 'X-Forwarded-For' and 'X-Real-IP' headers. The vulnerabilities could allow attackers to spoof client IPs and poison access and error logs, potentially bypassing authorization mechanisms.
