CVE-2018-11235

• Severity: high (CVSS 7.8 v3.0)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 48.1% probability of exploitation in the next 30 days
• Public exploit or detection template: yes
• Published: 2018-05-30 · updated 2026-06-17
• Weakness: CWE-22

Description

In Git before 2.13.7, 2.14.x before 2.14.4, 2.15.x before 2.15.2, 2.16.x before 2.16.4, and 2.17.x before 2.17.1, remote code execution can occur. With a crafted .gitmodules file, a malicious project can execute an arbitrary script on a machine that runs "git clone --recurse-submodules" because submodule "names" are obtained from this file, and then appended to $GIT_DIR/modules, leading to directory traversal with "../" in a name. Finally, post-checkout hooks from a submodule are executed, bypassing the intended design in which hooks are not obtained from a remote server.
