CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input. A remote attacker can send specially crafted packets to port 4506 and perform a denial of service (DoS) attack.
2) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2023-20898)

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a local user to bypass implemented security restrictions.
The vulnerability exists due to Git Providers get the same cache directory base name and can read from the wrong environment. A local user can gain access to sensitive information or corrupt data.
3) UNIX symbolic link following (CVE-ID: CVE-2023-34049)
CWE-ID: CWE-61 - UNIX Symbolic Link (Symlink) Following
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H/E:U/U:Clear
