There was a problem hiding this comment.
I think we need a safety net here. We don't know the length of the stream, and it could potentially be GB size.
If sanitizing the SVG as stream isn't possible, maybe we can read up to a maximum of 10MB (or some configurable value) and don't generate the preview if the file is too big.

Description
Bugfix: Apply SVG sanitization to all file content before using ImageMagick
Any file content is now sanitized for SVG threats before being processed by
ImageMagick, preventing potential security vulnerabilities.
