5) Code Injection
EUVDB-ID: #VU89490
Risk: High
CVSSv3.1: 7.8 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2024-32004
CWE-ID:
CWE-94 - Improper Control of Generation of Code ('Code Injection')
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a process control issue while cloning special-crafted local repositories. A remote attacker can execute arbitrary code on the target system.

6) UNIX Hard Link
EUVDB-ID: #VU91286
Risk: Medium
CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2024-32020
CWE-ID:
CWE-62 - UNIX Hard Link
