Once again this is not a Rust vulnerability.
This is a Windows vulnerability and Rust is simply the first set of tools to implement a workaround - since Microsoft can't do it without breaking backwards compatibility.
Somehow the narrative has turned into negative PR for Rust when in fact they are handling this vulnerability better than anyone else in the industry.
Both the article and the CVE description point to how Rust handles escaping for CMD arguments. If it's not a Rust issue then can you explain?
Because this is the status of the bug across the standard libraries of various languages, per this article and others:
Notably C and C++ are missing from this list because their standard libraries don't even offer this capability. Half of these standard libraries are responding to the issue by just warning you about it in the function documentation. Rust is one of the few that actually prevents the attack from happening.
The original BatBadBut bug report used JavaScript to illustrate the vulnerability.
