GHSA-vgxh-x8jv-hmff silverstripe/framework code execution vulnerability

• Packagist silverstripe/framework: >= 4.0.3-rc1, < 4.0.4 → fixed in 4.0.4 • Packagist silverstripe/framework: >= 4.1.0-rc1, < 4.1.1 → fixed in 4.1.1

There is a vulnerability whereby arbitrary global functions may be executed if malicious user input is passed through to in the second argument of `ViewableData::renderWith`. This argument resolves associative arrays as template placeholders. This exploit requires that user code has been written which makes use of the second argument in `renderWith` and where user input is passed directly as a value in an associative array without sanitisation such as `Convert::raw2xml()`. `ViewableData::customise` is not vulnerable.
