HIGH 7.5REMOTEUPGRADE
CVE-2026-73622 is a high-severity flaw (CVSS 7.5) affecting gitpython. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
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.
Why this priority
- High severity
- Public exploit reference
- Remotely exploitable, no login, no user action
A fixed release or distro patch exists.
