Updates Go requirement from 1.26.0 to 1.26.6 to address
stdlib vulnerabilities.

GO-2026-5932 (golang.org/x/crypto) has no fix available.
Use fix-state: not-fixed so the entry auto-expires when
a fix is published.

Signed-off-by: Daniel Farrell <dfarrell@redhat.com>
GO-xxx vulnerability IDs report fix.state='' (empty string) in the
grype DB, which matches fix-state: unknown, not fix-state: not-fixed.

Signed-off-by: Daniel Farrell <dfarrell@redhat.com>
CVE-2015-5237 and CVE-2021-22570 are no longer reported by grype;
the ignore entries are dead weight.

Review Change Stack

Walkthrough

The change updates Go requirements and dependencies in the root and tools modules. It also revises Grype vulnerability ignores by removing two protobuf entries and adding an x/crypto rule for GO-2026-5932.

Changes

Go dependencies and security policy

Layer / File(s) Summary
Module and dependency updates
go.mod, tools/go.mod
Both modules now require Go 1.26.6. Root and tools dependencies were upgraded, and new indirect dependencies were added.
Grype vulnerability ignore update
.grype.yaml
Removed two protobuf CVE ignores. Added an ignore for GO-2026-5932 affecting golang.org/x/crypto when the fix state is unknown.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🔵 Low · up to 2ff31

The dependency and vulnerability updates are localized, but both modules remain on Go 1.26.6, which may retain a known net/http h2c regression unless that baseline is intentionally constrained; the PR is otherwise mergeable with explicit owner follow-up.

Go 1.26.7 release date net/http fixes official

💡 Result:

Go 1.26.7 was released on August 19, 2026 [1][2]. This minor release includes a specific fix for a regression in the net/http package that affected unencrypted HTTP/2 (h2c) connections [2]. The breakage was introduced by a security patch included in the previous week's release (Go 1.26.6) [2][3]. Further technical details regarding this issue can be found in the Go issue tracker under issue 80876 [2].

Raise the Go patch baseline to 1.26.7.

Both modules declare Go 1.26.6. Go 1.26.7 fixes the net/http h2c regression in Go 1.26.6. CI and image builds do not pin another Go version, so update both declarations unless an external Shipyard constraint requires 1.26.6.
