MEDIUM

Why flagged The package downloads a prebuilt binary ZIP from spflashtools.com, which is a third-party WordPress-based site (not the official MediaTek or official SP Flash Tool distribution channel). The binary is executed directly on the user's system (flash_tool, a native Linux executable). The Referer header requirement is a minor oddity but not inherently malicious — it's common on WordPress download sites. The sha256sum is present and pinned, which mitigates substitution risk somewhat, but the source is still an unofficial redistributor of a closed-source binary tool. This is a genuine medium-severity supply-chain concern: a prebuilt closed-source binary from an unofficial third-party host with no way to verify it matches any authoritative upstream release. The risk is real but not evidence of active malice.
