Introduction Hello, I’m RyotaK ( @ryotkak ), a security engineer at Flatt Security Inc.
Recently, I reported multiple vulnerabilities to several programming languages that allowed an attacker to perform command injection on Windows when the specific conditions were satisfied.
Today, affected vendors published advisories of these vulnerabilities 1, so I’m documenting the details here to provide more information about the vulnerabilities and minimize the confusion regarding the high CVSS score.
Yeah, backwards compatibility is good when it isn’t a security issue.

I’ve gotten the question often enough about why and how. You don’t have to open it 🤷

Sorry.
