bilibili-live-helper-bin
A prebuilt binary (Electron app zip) is downloaded from s2.danmaku.live, which is a personal/project CDN rather than an official distribution channel like GitHub releases. The binary is installed directly to /opt and symlinked into /usr/bin, meaning it executes with full user privileges. The sha512sums are present and fixed, which mitigates substitution risk somewhat, but the host is not a well-known, audited mirror — if the domain is compromised or the file is swapped before the checksum was recorded, users would run arbitrary code. This is a classic medium-severity supply-chain concern: executed binary from an unofficial host with no reproducible build.
Triggered rules
source_untrusted_domain
One or more source=() URLs point to a host outside the trusted allowlist (github.com, gitlab.com, codeberg.org, pypi.org, …).
