NVD Description
Note: Versions mentioned in the description apply only to the upstream tinyproxy package and not the tinyproxy package as distributed by Echo.
See How to fix? for Echo:latest 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.
