Three review items addressed: * **Veria (Medium): SSRF via redirect.** ``fetch_validated_image_bytes`` was calling ``validate_url(url)`` once and then fetching with the default httpx client, so a 3xx to an internal IP would have been followed unvalidated. Switched to ``async_safe_get`` (the existing SSRF primitive used elsewhere in the codebase) which walks each redirect hop, re-validates, and rejects redirects to blocked networks. Default ``litellm.user_url_validation`` is True so protection is on out of the box. * **Greptile (P2): SVG can embed JS.** Removed ``image/svg+xml`` from the allowed-Content-Type set. The hardcoded response media type (``image/jpeg`` / ``image/x-icon``) means a real SVG body wouldn't render as SVG anyway in modern browsers — the allowlist entry was giving up XSS surface for no actual SVG-rendering benefit. If real SVG support is wanted later, that's a deliberate feature PR with CSP / nosniff bundled. * **Greptile (P2): cache-write OSError drops validated bytes.** When the upstream fetch succeeded but ``open(cache_path, "wb")`` raised (read-only assets dir), the bytes were discarded and the default logo was served — a silent regression for that deployment. Now serve the validated bytes inline via ``Response(...)`` as a fallback before falling back to default. Tests: - Replaced low-level mocks of ``validate_url`` with mocks of ``async_safe_get`` directly, exercising the helper's contract rather than the SSRF primitive's internals. - New ``test_rejects_svg_content_type`` confirms SVG is blocked. - ``test_get_image_cache_logic`` fixture now sets ``mock_response.is_redirect = False`` so ``async_safe_get`` doesn't treat the Mock's truthy attribute as a redirect.
