MEDIUM

Why flagged The package downloads a prebuilt .deb binary (containing a PKCS#11 shared library and application) from storagegw.estaleiro.serpro.gov.br, which is a subdomain of serpro.gov.br — Brazil's federal IT services agency (Serviço Federal de Processamento de Dados). This is the official vendor host for Serpro's software distribution infrastructure, not a random personal or unofficial host. The sha256sums are pinned, providing integrity verification. However, the concern is not zero: the binary is a prebuilt executable/library (libserproidp11.so) that gets installed into /usr/lib and loaded by browsers/applications as a PKCS#11 module — a highly privileged position. There is no source build, so users must trust the upstream binary entirely. This is a legitimate medium-risk pattern (prebuilt closed-source binary from a vendor host) rather than a clear attack, and the host is plausibly official. The cheaper model's concern about 'non-standard host' is partially a false positive since serpro.gov.br is a Brazilian government domain, but the prebuilt binary nature of the package is a genuine supply-chain consideration worth flagging as medium.

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