Background
git-annex is an open-source tool that manages files with git, without checking the file contents into git. It allows users to store large files in a distributed manner while keeping track of their locations. The tool is commonly used for version control and collaboration purposes. However, certain uses of git-annex were found to be vulnerable to a private data exposure and exfiltration attack.
Vulnerability Detail
The vulnerability in git-annex allows an attacker to exfiltrate private data from a victim's repository by exploiting control over one of the remotes. The attacker can provide a malicious git-annex repository that the victim clones or gain read access to the victim's repository. By running specific commands, the attacker can trick git-annex into following URLs pointing to private data, which is then transferred to the compromised remote. This attack is most likely to succeed when the victim is running the git-annex assistant or periodically syncing content.
