Doc Text:
A vulnerability was found in Git. Using a specially-crafted repository, Git can be tricked into using its local clone optimization even when using a non-local transport. Though Git will abort local clones whose source $GIT_DIR/objects directory contains symbolic links (CVE-2022-39253), the objects directory may still be a symbolic link.

Description TEJ RATHI 2023-02-08 10:44:14 UTC 
Using a specially-crafted repository, Git can be tricked into using its local clone optimization even when using a non-local transport. Though Git will abort local clones whose source $GIT_DIR/objects directory contains symbolic links (c.f., CVE-2022-39253), the objects directory itself may still be a symbolic link.

These two may be combined to include arbitrary files based on known paths on the victim's filesystem within the malicious repository's working copy, allowing for data exfiltration in a similar manner as CVE-2022-39253.
