What is GHSA-vgxh-x8jv-hmff?
GHSA-vgxh-x8jv-hmff is a code injection vulnerability in silverstripe/framework, published on 27 May 2024. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
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.
