CVE-2022-1884

A remote command execution vulnerability exists in gogs/gogs versions <=0.12.7 when deployed on a Windows server. The vulnerability arises due to improper validation of the tree_path parameter during file uploads.

If the core.sshCommand is set, this can lead to remote command execution.
