Two open Dependabot alerts, both against github.com/go-git/go-git/v6, a
transitive dependency of github.com/pulumi/pulumi/sdk/v3 by way of
common/workspace:
CVE-2026-71556 (high, 7.1) worktree operations may follow symlinks,
allowing writes outside the worktree
CVE-2026-71557 (medium, 6.3) malicious reference names may resolve
outside the reference storage
Both are fixed in v6.0.0-alpha.5. The Pulumi SDK is already at its latest
release (v3.258.0) and still requires alpha.4, so bumping the direct
dependency does not help; an explicit minimum-version entry is the
remedy. go-billy comes along as a consequence.
Also pins toolchain go1.26.6. govulncheck reported six reachable
standard-library vulnerabilities from building on go1.26.4 -- ASN.1, TLS,
net/url, net/http and os -- all fixed in 1.26.5/1.26.6. Dependabot does
not track the Go standard library, so nothing alerted on these, but they
were reachable from pulumi.Run and dns.LookupManagedZone. Pinning the
floor in go.mod means every build gets a patched stdlib rather than
whatever the build host happens to have.
govulncheck now reports no vulnerabilities.
Not addressed, deliberately: GO-2026-5932 flags golang.org/x/crypto/openpgp
as unmaintained and unsafe by design. It has no fixed version, and our
code does not call it. Upgrading x/crypto to v0.55.0 was tried and does
not clear it, so that change was dropped to keep this diff minimal.
