RISK

Why place_media_on_site is rated Medium

The tool modifies site content by replacing image sources, which is a write operation. While the description emphasizes safety features (checksum, lock, undo-compatibility), the fundamental operation is creating or modifying data (image placement on a site). It is not destructive since changes can be undone, not executable code, and not financial.

From the tool's definition Tool description states it 'inserts an uploaded file (image) on a specific site location — replaces src in a found <img> tag' and is described as 'Undo-compatible checkpoint'. This is a reversible modification of site content.
