_⚠️ Potential issue_ | _🟠 Major_

**Validate URL scheme to prevent SSRF or local file access.**

`urllib.request.urlretrieve` can be exploited with `file://` or custom schemes, potentially leading to SSRF or local file access vulnerabilities. Validate the URL scheme before downloading.

```
In `@packages/core/ai_content_platform/vimax/adapters/image_adapter.py` around
lines 257 - 264, The _download_image method currently calls
urllib.request.urlretrieve directly which allows dangerous schemes (e.g.,
file://) and can lead to SSRF/local access; before calling urlretrieve, parse
the input URL (e.g., with urllib.parse.urlparse) and verify the scheme is
strictly "http" or "https" (or explicitly allowed list), log a warning and
skip/raise if not allowed, and only then proceed to download; keep the existing
exception handling around urllib.request.urlretrieve but ensure the validation
prevents non-HTTP(S) schemes from reaching urlretrieve.
