No SLSA provenance npm registry signatures gitHead linked

Without SLSA provenance there is no cryptographic link between this tarball and the public source — the axios compromise (March 2026) relied on exactly this gap.

Accepted risks

Findings the reviewer chose to accept rather than block on.

SourceRuleReasonAccepted byWhen
typosquat typosquat.levenshtein:dotenv AI (typosquat): osenv is a legitimate, 13+ year old package by isaacs (npm creator) for OS environment lookups. Not a typosquat of dotenv — different purpose, different author, predates dotenv. ai
license uncommon-license:BSD AI (license): BSD is a well-known permissive license; the uncommon-license finding is a false positive for this package. ai
bogus-package bogus-package AI (bogus-package): isaacs is the creator of npm; S_KNOWN_SPAM_PUBLISHER flag is a clear false positive for this publisher. ai
provenance publisher-changed AI (provenance): Publisher change from iarna to isaacs is a transition between two well-known npm core maintainers; both are trusted. ai
semgrep semgrep:child-process-import AI (semgrep): child_process is core to osenv's purpose: falling back to shell commands (whoami, hostname) when env vars are unset. ai
provenance no-provenance AI (provenance): Package predates Sigstore provenance; no CI/CD provenance expected for packages of this era. ai
