Details

The standard library net/http package dependency used by File Browser improperly accepts a bare LF as a line terminator in chunked data chunk-size lines. I 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.
