Description Cedric Buissart 2019-09-11 14:14:49 UTC

wget is affected by a behavior similar to CVE-2018-1000007 (curl) : when given a `Authorization` header, wget will reuse it by default on the 2nd server if the first replies with a 3xx redirect.
This possibly mean a leak of credentials to the 2nd server.

Note: this does not happen when username/password are provided using the regular options (e.g.: --user & --password)
