• CVE-2026-42505 (Moderate, CVSS 5.3) — Go stdlib, fixed in Go 1.26.5

Changes

• Updated go.mod Go version directive: go 1.26.0 → go 1.26.5

This PR addresses only the Go stdlib CVEs. The remaining CVEs in ROSAENG-63302 are in base-image RPM packages and require a base image update through boilerplate.
