How to fix
Restrict repository access to trusted sources and avoid cloning or working with repositories from untrusted origins until upgrading.
Technical details
The vulnerability exists in how Aider auto-loads .aider.conf.yml configuration files without a user trust prompt. An attacker can set the "notifications-command" or "editor" configuration values to arbitrary shell commands, which are then executed via Python's subprocess with shell=True after model responses or /editor command invocation. This requires local or network access to place the malicious config in the repository, but no authentication or user interaction beyond normal tool usage is needed to trigger execution.
