Improper Neutralization of Argument Delimiters in a Command in GitPython - CVE-2026-76220

Vulnerability identifier: #VU140973

CSH Severity: Medium

CVSS v4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]

CVE-ID: CVE-2026-76220

CWE-ID: CWE-88

Exploitation vector: Remote access

Exploit availability: No public exploit available

The vulnerability allows a remote user to execute arbitrary commands.

The vulnerability exists due to improper neutralization of argument delimiters in a command in the unsafe option guard for git kwargs handling when processing user-controlled keyword arguments with split_single_char_options disabled. A remote user can supply a crafted single-character option value that is transformed into a joined short-option token to execute arbitrary commands.

Exploitation requires an application to forward a user-controlled kwargs dictionary to a guarded GitPython method such as clone_from, fetch, pull, push, ls_remote, iter_commits, blame, or archive.
