Security: vulnerable dependency image-size (CVE-2025-71329/71330) — maintained drop-in available

[lcf2212dev]

Context

This package depends on npm image-size. Upstream is archived and the latest release (2.0.2) remains affected by:

• CVE-2025-71329 — DoS via infinite loop (JXL/HEIF/JP2 zero-size boxes)
• CVE-2025-71330 — DoS via infinite loop (ICNS zero entry length)

npm audit fix will not switch package names automatically.

Maintained drop-in

• GitHub: https://github.com/lcf2212dev/image-size-next
• Announcement: https://github.com/lcf2212dev/image-size-next/blob/main/ANNOUNCE.md
