UNIX Hard Link in Git - CVE-2024-32020

Vulnerability identifier: #VU91286

CSH Severity: Medium

CVSS v4 BT: 4 [CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2024-32020

CWE-ID: CWE-62

Exploitation vector: Remote access

Exploit availability: No public exploit available

The vulnerability allows a remote attacker to compromise the original repository.

The vulnerability exists due to insecure hardlink following when working with local clones. Local clones may end up hardlinking files into the target repository's object database when source and target repository reside on the same disk. If the source repository is owned by a different user, then those hardlinked files may be rewritten at any point in time by the untrusted user.
