Why flagged

The PKGBUILD downloads a prebuilt binary .deb from mirrors.sdu.edu.cn (a Chinese university mirror hosting the Spark Store repository), which is not the official upstream source. The package installs executed binaries (ablrun script and additional-base-lib shared libraries) extracted from this .deb. While mirrors.sdu.edu.cn is a legitimate Chinese university mirror that hosts the Spark Store (a third-party Deepin/Ubuntu app store), it is not the canonical upstream host for this package, and the Gitee URL listed as the project URL is a different location entirely. The sha256sum provides some integrity protection, but if the mirror were compromised or the hash were updated to match a malicious payload, arbitrary code execution would result at runtime. This is a genuine supply-chain concern: prebuilt binaries from a non-canonical third-party host being installed as executable libraries/scripts. The risk is real but not clearly malicious — consistent with a MEDIUM rating.

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, …).
