Detailsinfo

A vulnerability classified as critical was found in Hmbown CodeWhale up to 0.8.63. This vulnerability affects an unknown code of the file .codewhale/config.toml. The manipulation of the argument allow_shell with an unknown input leads to a os command injection vulnerability. The CWE definition for the vulnerability is CWE-78. The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

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.

The advisory is shared for download at github.com. This vulnerability was named CVE-2026-75911 since 08/18/2026. The exploitation appears to be easy. The attack can be initiated remotely. No form of authentication is required for a successful exploitation. Successful exploitation requires user interaction by the victim. There are known technical details, but no exploit is available. The current price for an exploit might be approx. USD $0-$5k (estimation calculated on 08/18/2026). The MITRE ATT&CK project declares the attack technique as T1202.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
