From the upstream release notes¹: With a crafted URL that contains a newline or empty host, or lacks a scheme, the credential helper machinery can be fooled into providing credential information that is not appropriate for the protocol in use and host being contacted. Unlike the vulnerability CVE-2020-5260 fixed in v2.17.4, the credentials are not for a host of the attacker's choosing; instead, they are for some unspecified host (based on how the configured credential helper handles an absent "host" parameter). The attack has been made impossible by refusing to work with under-specified credential patterns. ¹ https://www.kernel.org/pub/software/scm/git/docs/RelNotes/2.17.5.txt
