What is CVE-2019-13139?
CVE-2019-13139 is a high-severity command injection vulnerability in n/a, published on 22 Aug 2019. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
In Docker before 18.09.4, an attacker who is capable of supplying or manipulating the build path for the "docker build" command would be able to gain command execution. An issue exists in the way "docker build" processes remote git URLs, and results in command injection into the underlying "git clone" command, leading to code execution in the context of the user executing the "docker build" command. This occurs because git ref can be misinterpreted as a flag.
Weakness: CWE-78
