Pull Request Overview

This PR is currently not up to standards because it introduces high-severity security vulnerabilities via the golang.org/x/net dependency. Although the update to golang.org/x/crypto is intended to provide security fixes, the current version of the network library is susceptible to privilege escalation (CVE-2026-39821) and arbitrary code execution (CVE-2026-25681, CVE-2026-27136). These vulnerabilities constitute a major security flaw that prevents merging. Additionally, there is a missing verification step for project compilation that must be addressed to ensure the new dependency graph is stable.

Test suggestions

• Verify that the project compiles successfully with the updated versions of golang.org/x/crypto and its related indirect dependencies.

_{🔴 HIGH RISK}

The version of golang.org/x/net introduced in this update is affected by high-severity security vulnerabilities, including privilege escalation through incorrect Punycode label processing (CVE-2026-39821) and multiple Cross-Site Scripting (XSS) vectors that can lead to arbitrary code execution (CVE-2026-25681, CVE-2026-27136). This dependency should be updated to a patched version to mitigate these risks.
