Why flagged

The package downloads a prebuilt binary .deb from xuanim.com (the official project domain matching url='https://xuan.im', with xuanim.com being the download mirror for the same project). The sha512sums are present and pin the binary. However, this is still a prebuilt Electron application binary extracted from a .deb and installed directly — not built from source — and the host is not a major distribution mirror. The sha512sum for the .deb appears to be only 127 hex characters (should be 128 for SHA-512), which is suspicious and may indicate a truncated/corrupted checksum, potentially weakening integrity verification. The actual risk is a prebuilt binary from a semi-official but small vendor host with a potentially malformed checksum, which warrants medium severity as a supply-chain concern.

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, …).
