Affected versions

Symfony versions <5.4.46; >=6, <6.4.14; >=7, <7.1.7 of the Symfony Process component are affected by this security issue.

The issue has been fixed in Symfony 5.4.46, 6.4.14, and 7.1.7.

Description

On Window, 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 for branch 5.4.

Credits

We would like to thank Jordi Boggiano for reporting the issue and Nicolas Grekas for providing the fix.
