Summary
GitPython before 3.1.55 fails to disable environment variable expansion in Remote.create() and Submodule.add() URL handling, allowing attackers to exfiltrate secrets by supplying URLs containing variable references.
Attackers can craft URLs with environment variable tokens that are expanded into.git/config and.gitmodules, then transmitted to attacker-controlled hosts during fetch or pull operations. A flaw was found in GitPython.
This vulnerability allows a remote attacker to exfiltrate sensitive information, such as environment variables, by crafting malicious URLs. Red Hat severity: Important — CVSS 7.5 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N).
