    copier is an A library for rendering project templates.

    Affected versions of this package are vulnerable to UNIX Symbolic Link (Symlink) Following via the symlink resolution process in safe templates when _preserve_symlinks is set to true. An attacker can overwrite arbitrary files on the filesystem, within the user's write permissions, by crafting a malicious template that uses the generated directory structure functionality.

    Upgrade copier to version 9.11.2 or higher.

    UNIX Symbolic Link (Symlink) Following

    copier is an A library for rendering project templates.

    Affected versions of this package are vulnerable to UNIX Symbolic Link (Symlink) Following via the symlink resolution process in safe templates when _preserve_symlinks is set to false. An attacker can access arbitrary files or directories outside the intended template location by crafting malicious templates that include symlinks pointing to sensitive files.

    Note: Safe templates are those that don't use unsafe features like custom Jinja extensions, which would require passing the --UNSAFE,--trust flag.

    How to fix UNIX Symbolic Link (Symlink) Following?

    Upgrade copier to version 9.11.2 or higher.
