Why flagged

This PKGBUILD downloads and installs a prebuilt closed-source binary (flash_tool) from spflashtools.com, which is a third-party aggregator/mirror site rather than the official MediaTek/SP Flash Tool vendor. The binary is executed directly on the user's system with LD_LIBRARY_PATH set to its own directory. While sha256sums are present (providing integrity checking against the specific file at time of packaging), the host is not an official vendor distribution channel — spflashtools.com is a community mirror that could substitute binaries without the maintainer's knowledge. The 'unknown' license also indicates the provenance is unclear. This is a genuine medium-severity supply-chain concern: an unofficial host serving executed binaries, not a false positive.

Triggered rules

Medium source=() URL on a non-standard host source_untrusted_domain

One or more source=() URLs point to a host outside the trusted allowlist (github.com, gitlab.com, codeberg.org, pypi.org, …).
