No clear evidence of intentional malware/backdoor behavior is present in the fragment. The dominant security risk is the downloader’s pattern: it can fetch attacker-influenced URLs via curl without a strict destination allowlist in the shown code (enabling SSRF-like risk depending on how URL resolution behaves elsewhere). Additionally, SVG is accepted based on a superficial prefix heuristic without sanitization; if SVG is later rendered as active content, this can become a downstream XSS/security issue. Recommended review actions include enforcing URL scheme/host allowlists before curl, limiting download size, and ensuring SVG is sanitized or treated as non-executable/plain content depending on downstream rendering.
