Improper Neutralization of Special Elements in Output Used by a Downstream Component in GitPython - CVE-2026-69097

Vulnerability identifier: #VU139089

CSH Severity: Medium

CVSS v4: 7.1 [CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]

CVE-ID: CVE-2026-69097

CWE-ID: CWE-74

Exploitation vector: Remote access

Exploit availability: No public exploit available

The vulnerability allows a remote attacker to execute arbitrary code.

The vulnerability exists due to improper neutralization of special elements in git config section names in the GitPython config writer when writing attacker-controlled submodule names into the parent repository's .git/config. A remote attacker can supply a specially crafted submodule name to inject arbitrary config directives and execute arbitrary code.

User interaction is required for the victim to perform a subsequent git operation that uses the injected configuration, and the issue is reachable via untrusted .gitmodules data during submodule initialization or via applications that create submodules from untrusted input.
