How to fix?

There is no fixed version for Debian:unstable tinyproxy.

NVD Description

Note: Versions mentioned in the description apply only to the upstream tinyproxy package and not the tinyproxy package as distributed by Debian. See How to fix? for Debian:unstable relevant fixed versions and status.

Tinyproxy through 1.11.3 is vulnerable to HTTP request parsing desynchronization due to a case-sensitive comparison of the Transfer-Encoding header in src/reqs.c. The is_chunked_transfer function uses strcmp to compare the header value against "chunked", even though RFC 7230 specifies that transfer-coding names are case-insensitive.
