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

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.

Root Cause Analysis

The vulnerability stems from how template placeholder values were processed in renderWith's second argument. The commit adds '!is_string()' guards before is_callable() checks across multiple files to prevent string-based function execution. SSViewer_DataPresenter::processTemplateOverride directly handles template overrides passed to renderWith, making it the primary vector. The test case added in SSViewerTest.php demonstrates this by verifying that string values like 'phpinfo' are no longer executed as functions. Other modified functions (FixtureBlueprint, GridFieldDataColumns, MarkedSet) show similar patterns but are less directly tied to the described renderWith exploitation scenario.
