Details
As written in the advisory (Markdown source, shown as plain text).
### Impact
The malicious user is able to update a crafted `config` file into repository's `.git` directory in combination with crafted file deletion to gain SSH access to the server on case-insensitive file systems. All installations with [repository upload enabled (default)](https://github.com/gogs/gogs/blob/f36eeedbf89328ee70cc3a2e239f6314f9021f58/conf/app.ini#L127-L129) on case-insensitive file systems (Windows, macOS, etc.) are affected.
### Patches
Make sanitization of upload path to `.git` directory to be case-insensitive. Users should upgrade to 0.12.11 or the latest 0.13.0+dev.
### Workarounds
Disable [repository upload](https://github.com/gogs/gogs/blob/f36eeedbf89328ee70cc3a2e239f6314f9021f58/conf/app.ini#L127-L129).
