HIGH

Symfony vulnerable to command execution hijack on Windows with Process class

Published November 6, 2024Updated September 10, 2026Source: osv

Summary

### Description On Windows, when an executable file named `cmd.exe` is located in the current working directory it will be called by the `Process` class when preparing command arguments, leading to possible hijacking. ### Resolution The `Process` class now uses the absolute path to `cmd.exe`. The patch for this issue is available [here](https://github.com/symfony/symfony/commit/18ecd03eda3917fdf901a48e72518f911c64a1c9) for branch 5.4. ### Credits We would like to thank Jordi Boggiano for reporting the issue and Nicolas Grekas for providing the fix.
