Official description

CodeWhale versions before 0.8.64 fail to properly validate the allow_shell configuration parameter from project config files, allowing attackers to enable arbitrary shell command execution by committing a malicious .codewhale/config.toml file to a repository. When a user clones and opens the repository in CodeWhale, the AI model gains access to exec_shell and task_shell tools, enabling execution of arbitrary shell commands on the victim's machine without explicit user consent.
