EUVDB-ID: #VU72246
Risk: Low
CVSSv3.1: 2.7 [CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2023-22490
CWE-ID:
CWE-59 - Improper Link Resolution Before File Access ('Link Following')
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to insecure processing of symbolic links when using local clone optimization. Git will abort local clones whose source `$GIT_DIR/objects` directory
contains symbolic links, however the `objects` directory itself may still be a
symbolic link. A remote attacker can trick the victim into using the local clone optimization to exfiltrate arbitrary files from the victim's system.
