Description

This security bulletin contains information about 1 vulnerability.


1) Link following (CVE-ID: CVE-2026-111760)

CWE-ID: CWE-59 - Improper Link Resolution Before File Access ('Link Following')

CVSSv4: 7.3 [CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote user to execute arbitrary code on a victim's system.

The vulnerability exists due to improper symbolic link handling in Git's submodule cloning logic when processing recursive clones. A remote user can trick a victim into cloning a specially crafted, attacker-hosted repository with --recurse-submodules to execute arbitrary code by replacing a submodule gitfile with a symbolic link to a directory containing malicious configuration or hooks.
