NVD Description

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

The net/http package improperly accepts a bare LF as a line terminator in chunked data chunk-size lines. This can permit request smuggling if a net/http server is used in conjunction with a server that incorrectly accepts a bare LF as part of a chunk-ext.
