Input validation error in Git - CVE-2022-39253

Vulnerability identifier: #VU68517

CSH Severity: Low

CVSS v4: 1.8 [CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:A/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N]

CVE-ID: CVE-2022-39253

CWE-ID: CWE-20

Exploitation vector: Remote access

Exploit availability: Public exploit is available

The vulnerability allows a remote attacker to bypass certain security restrictions.

The vulnerability exists due to the way Git handles hardlinks when performing a local clone. A remote attacker can trick the victim into clocking a malicious repository and create or copy hardlinks to critical files on the system, which can result in sensitive information exposure.
