[4.2.x] Fixed CVE-2025-48432 -- Escaped formatting arguments in `log_response()`.
Suitably crafted requests containing a CRLF sequence in the request
path may have allowed log injection, potentially corrupting log files,
obscuring other attacks, misleading log post-processing tools, or
forging log entries.
To mitigate this, all positional formatting arguments passed to the
logger are now escaped using "unicode_escape" encoding.
Thanks to Seokchan Yoon (https://ch4n3.kr/) for the report.
