CVE-2026-75911: CodeWhale versions before 0.8.64 fail to properly validate the allow_shell configuration parameter from projec

Routine

HIGH 7.8

CVE-2026-75911 is a high-severity flaw (CVSS 7.8) affecting affected software. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

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
