Why flagged

The PKGBUILD downloads a prebuilt .asar file from a specific GitLab CI job artifact URL (job ID 13795436076). While the source is pinned to a specific job artifact and has a sha256sum, CI job artifacts on GitLab can be deleted and re-uploaded or the artifact URL can point to different content if the job is re-run. More importantly, this .asar file replaces the official TETR.IO app.asar in the installed Electron application — meaning it is executed code from a third-party (UniQMG's tetrio-plus project, not the official TETR.IO vendor). The sha256sum does provide integrity verification at download time, which mitigates silent substitution risk somewhat. However, the core concern remains: an unofficial, prebuilt Electron application bundle (asar) from a personal GitLab project is being substituted for the official application code and will be executed by the Electron runtime. This is a genuine supply-chain concern — if the artifact were ever replaced or the checksum removed/changed in a future pkgrel, users would run arbitrary third-party code. The sha256sum pinning keeps this at medium rather than high, but the pattern of replacing official app code with a prebuilt third-party artifact is a real supply-chain risk.

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, …).
