What is CVE-2022-23773?

In certain versions of the Go programming language, an access control misconfiguration arises from the misinterpretation of branch names as version tags. This vulnerability permits actors who should only have permissions to create branches to bypass restrictions and potentially create tags, leading to unauthorized actions within the source control ecosystem.

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
