theshit vulnerable to unsafe loading of user-owned Python rules when running as root.

theshit is a command-line utility that automatically detects and fixes common mistakes in shell commands. Prior to version 0.1.1, the application loads custom Python rules and configuration files from user-writable locations (e.g., `~/.config/theshit/`) without validating ownership or permissions when executed with elevated privileges. If the tool is invoked with `sudo` or otherwise runs with an effective UID of root, it continues to trust configuration files originating from the unprivileged user's environment. This allows a local attacker to inject arbitrary Python code via a malicious rule or configuration file, which is then executed with root privileges. Any system where this tool is executed with elevated privileges is affected. In environments where the tool is permitted to run via `sudo` without a password (`NOPASSWD`), a local unprivileged user can escalate privileges to root without additional interaction. The issue has been fixed in version 0.1.1. The patch introduces strict ownership and permission checks for all configuration files and custom rules. The application now enforces that rules are only loaded if they are owned by the effective user executing the tool. When executed with elevated privileges (`EUID=0`), the application refuses to load any files that are not owned by root or that are writable by non-root users. When executed as a non-root user, it similarly refuses to load rules owned by other users. This prevents both vertical and horizontal privilege escalation via execution of untrusted code. If upgrading is not possible, users should avoid executing the application with `sudo` or as the root user. As a temporary mitigation, ensure that directories containing custom rules and configuration files are owned by root and are not writable by non-root users. Administrators may also audit existing custom rules before running the tool with elevated privileges.

The Shit 安全漏洞

The Shit是AsfhtgkDavid个人开发者的一个用于自动检测和修复shell命令中的常见错误的命令行实用程序。 The Shit 0.1.1之前版本存在安全漏洞，该漏洞源于以高权限运行时未验证配置文件和规则的所有权，可能导致权限提升。
