Description

Aider through 0.86.2 contains a command execution vulnerability that allows attackers to run shell commands by committing a malicious .aider.conf.yml that is auto-loaded without a trust prompt. Attackers can set notifications-command or editor values that are executed via subprocess with shell=True after model replies or /editor use, running commands with the victim's privileges.
