## How to fix

## Technical details

The vulnerability exists in ThemeModule::startImport() which extracts uploaded ZIP archives directly into the public web root without validating filenames, extensions, or content. An authenticated administrator can upload a crafted theme containing PHP files and .htaccess configuration to re-enable PHP execution in directories where it would normally be disabled, then request the uploaded PHP file to execute arbitrary OS commands as the web server user. The fix involves filtering dangerous files during theme import.
