CVE-2022-4018 Missing Authentication for Critical Function in GitHub repository ikus060/rdiffweb prior to 2.5.0a6

GitHub users may have encountered the following message when trying to clone, fork, pull, or push to a repository: GitHub users may have encountered the following message when trying to clone, fork, pull, or push to a repository: The remote end may have rejected your request because it appears that the remote repository has been updated recently. You may be seeing this error because the remote repository has changed since the last time you synchronized with it. This usually means that someone else has pushed some code to the remote repository. You can resolve this issue by doing the following: Go to the settings of the repository and click Synchronize Now. This will update the remote repository with your latest changes. The issue with the above message is caused by the fact that the remote repository was updated by a third party and not by the original owner of the repository. As a result, the remote repository would appear as updated on GitHub, which would cause all attempts to clone, fork, pull, or push to fail. To solve this, you will have to change the remote server address to point to the original server and not the clone URL. To do that, go to the settings of the repository, click on the GitHub icon on the top right corner and select Settings. In the Settings page, go to the Remote tab. In the URL field, put the original server address (i.e. https://github.com/user_name/Repo_name). Now press the Update button.

How to Prevent Remote Repositories from Being Synchronized

GitHub has a feature called remote repositories that allows users to manage their local repository and the remote one separately. This allows users to clone, fork, pull, or push without having to wait for the remote repository to sync. Synchronizing can cause problems such as the above message. To prevent this from happening, you will have to change the default URL of your repository so that it points back to what it was originally.

Pushing a commit to GitHub

When you push a commit to GitHub, the remote repository will appear as updated. The server address will point to the original repository and not the clone URL.

SSH Key Fingerprinting

SSH is a way of securely typing into a remote computer. This method allows you to encrypt the data between the two computers before it goes over the wire. To authenticate, you need to use an SSH key and share it with the other party. If someone hacks your account, they could log in using your password and then access any repository that uses this method of authentication.
SSH keys provide a way for users to easily identify themselves without having to type their password every time they log in. That's what makes SSH keys so great; they are easy to use and hard for someone else to guess. However, SSH key fingerprinting has some drawbacks as well.
The main problem with SSH keys is that anyone who has access can potentially read your key. This means that you may be sharing your public key with people who shouldn't have access or even individuals from abroad that could only be trusted by a VPN connection. Because of this, you should make sure you don't share your public key publicly or share it with unauthorized parties such as friends and family members who should not have access to sensitive information on your computer.
