Vulnerability details
The vulnerability allows a remote attacker to execute arbitrary code.
The vulnerability exists due to improper neutralization of OS command elements in the blockUnsafeOperationsPlugin configuration-write denylist when processing attacker-influenced custom arguments for git.clone(). A remote attacker can supply a crafted include configuration argument that loads an attacker-controlled git configuration file to execute arbitrary code.
Exploitation requires attacker-writable storage that is readable by the simple-git process.
