1) Protection Mechanism Failure (CVE-ID: CVE-2025-47910)

2) Input validation error (CVE-ID: CVE-2025-47906)

The vulnerability allows a local user to escalate privileges on the system.

3) Link following (CVE-ID: CVE-2025-26625)

The vulnerability allows a remote attacker to overwrite arbitrary files on the system.

The vulnerability exists due to an insecure link following issue. When populating a Git repository's working tree with the contents of Git LFS objects, certain Git LFS commands may write to files visible outside the current Git working tree if symbolic or hard links exist which collide with the paths of files tracked by Git LFS. A remote attacker can write arbitrary files using crafted links, leading to remote code execution.
