Summary

Aider through 0.86.2 runs shell commands taken from a repository's .aider.conf.yml file. The tool loads this file automatically without a trust prompt and passes its notifications-command or editor values to a shell (CWE-78). An attacker who commits a malicious file can run commands with the privileges of a victim who uses Aider in that repository.

Description from the CNA

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.
