Summary

  • Bump the build stage from golang:1.25-alpine3.22 to golang:1.25-alpine3.23.
  • Bump the runtime image from alpine:3.22 to alpine:3.23.

Alpine 3.23 is the current stable release (2025-12-03). Rebuilding on the newer base pulls in busybox 1.37.0-r20+ (CVE-2024-58251, BusyBox netstat ANSI-escape DoS) and Go 1.25.10 via golang:1.25-alpine3.23 (CVE-2025-58183, archive/tar unbounded sparse-region allocation, fixed in 1.25.9).

Move the build stage and final image to alpine 3.23 (current
stable, released 2025-12-03) so that a rebuild picks up:

- busybox 1.37.0-r20+ (addresses CVE-2024-58251, BusyBox netstat
  ANSI-escape DoS)
- Go 1.25.10 via golang:1.25-alpine3.23 (addresses CVE-2025-58183,
  archive/tar unbounded sparse-region allocation, fixed in 1.25.9)
