Greptile Summary

This dependabot PR bumps golang.org/x/net from v0.45.0 to v0.55.0 to address multiple CVEs (including XSS via duplicate attributes, several HTML-parser correctness issues, and a DoS in the HTML parser). Because v0.55.0 requires Go 1.25, the PR also promotes the module's go directive from go 1.24.0 / toolchain go1.24.2 to go 1.25.0, and correspondingly upgrades golang.org/x/crypto, sync, sys, term, text, mod, and tools.

• Security fixes: Patches CVE-2026-42506, CVE-2026-42502, CVE-2026-25680, CVE-2026-25681, CVE-2026-27136, and CVE-2026-39821 in the html and idna sub-packages of golang.org/x/net.
• Go version bump: The go directive moves to 1.25.0 (a hard minimum enforced by the Go toolchain since Go 1.21), but all three CI workflows still pin go-version: 1.21.3, which will cause every build to fail until those workflow files are updated.

Confidence Score: 3/5

The dependency upgrades themselves are straightforward security patches, but the implicit Go 1.25 toolchain requirement introduced by net v0.55.0 will break all three CI workflows, which still pin Go 1.21.3.

The three GitHub Actions workflows all specify go-version: 1.21.3, while the updated go.mod now declares go 1.25.0 as the minimum. Go has enforced the go directive as a hard toolchain floor since 1.21, so every CI run — pre-release builds, tagged releases, and example verification — will error out immediately on version mismatch until the workflow files are updated. The security motivation for merging is strong, but the CI breakage needs to be resolved first or in a follow-up before the branch is functional.

.github/workflows/pre-release.yml, .github/workflows/tagged-release.yml, and .github/workflows/verify-example.yml all need their go-version updated to at least 1.25.

Important Files Changed

Filename	Overview
go.mod	Bumps golang.org/x/net to v0.55.0 and several companion x/ packages; also promotes the go directive from 1.24.0 to 1.25.0 (required by net v0.55.0), but CI workflows still pin Go 1.21.3, which will break all builds.
go.sum	Hash entries updated to match all bumped golang.org/x/* packages; no anomalies in the checksum file.

### Issue 1 of 1
go.mod:4
**CI workflows incompatible with new Go 1.25 minimum**

`golang.org/x/net v0.55.0` requires Go 1.25 in its own `go.mod`, so dependabot has promoted this module's `go` directive from `go 1.24.0` to `go 1.25.0`. All three GitHub Actions workflows (`.github/workflows/pre-release.yml`, `tagged-release.yml`, `verify-example.yml`) pin `go-version: 1.21.3`. Since Go 1.21 enforces the `go` directive as a hard minimum, any build on those workflows will immediately fail with a toolchain version mismatch error, blocking every push to `main` and every tagged release until the workflow files are updated to at least `go-version: 1.25`.
