Starting in version 0.24.0 and prior to version 1.2.5, Dulwich&#39;s `ProcessMergeDriver` substitutes the file path (from the git tree, controllable by an attacker via a malicious branch) into the merge driver command via the `%P` placeholder and executes it with `subprocess.run(..., shell=True)`. An attacker who can cause a victim to merge an untrusted branch can achieve arbitrary command execution by crafting malicious file paths. Version 1.2.5 fixes the issue.</p> <p><strong>Affected:</strong> jelmer dulwich</p> <p>Dulwich is a pure-Python implementation of the Git file formats and protocols.
