fix: patch Snyk x/crypto SSH and Go stdlib vulnerabilities#100
Merged
Conversation
Bump golang.org/x/crypto replace directive from v0.50.0 to v0.52.0 to fix 11 CVE-2026-* vulnerabilities in x/crypto/ssh, ssh/agent, and ssh/knownhosts. Bump Go from 1.26.2 to 1.26.3 to fix 8 stdlib vulns in std/net, net/http, html/template, net/mail, and net/http/httputil. Update .snyk safety-net ignores for the new CVEs (transitive ghost deps that Snyk may still flag despite the replace directive).
✅ Snyk checks have passed. No issues have been found so far.
💻 Catch issues earlier using the plugins for VS Code, JetBrains IDEs, Visual Studio, and Eclipse. |

Update section comment from "not in go.mod" to "not a direct require" since a replace directive for x/crypto does exist in go.mod.
