    Symfony's incorrect argument escaping under MSYS2/Git Bash can lead to destructive file operations on Windows

    CVE-2026-24739 · GHSA-r39x-jcww-82v6

    Affected
    • Packagist symfony/process < 5.4.51; >= 6.4, < 6.4.33; >= 7.3, < 7.3.11; >= 7.4, < 7.4.5; >= 8.0, < 8.0.5

    7.4.56.4.337.3.118.0.55.4.51· Vendor fix available
    Issue
    The Symfony Process component did not correctly treat some characters (notably =) as “special” when escaping arguments on Windows. When PHP is executed from an MSYS2-based environment (e.g. Git Bash) and Symfony Process spawns native Windows executables, MSYS2’s argument/path conversion can mishandle unquoted arguments containing these characters. This can cause the spawned process to receive corrupted/truncated arguments compared to what Symfony intended. Impact If an application (or tooling such as Composer scripts) uses Symfony Process to invoke file-management commands (e.g. rmdir, del, etc.) with a path argument containing =, the MSYS2 conversion layer may alter the argument at runtime. In affected setups this can result in operations being performed on an unintended path, up to and including deletion of the contents of a broader directory or drive. The issue is particularly relevant when untrusted input can influence process arguments (directly or indirectly, e.g. via…

    Symfony vulnerable to command execution hijack on Windows with Process class

    CVE-2024-51736 · GHSA-qq5c-677p-737q

    Affected
    • Packagist symfony/process < 5.4.46; >= 6.0.0, < 6.4.14; >= 7.0.0, < 7.1.7
    Fixed in
    5.4.466.4.147.1.7· Vendor fix available
    Issue
    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 for branch 5.4. Credits We would like to thank Jordi Boggiano for reporting the issue and Nicolas Grekas for providing the fix.

    Recommended action: Upgrade to 7.1.7, 6.4.14 or 5.4.46 by release line, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
