- Active Storage disables libvips unfuzzed image loaders/savers, causing Vips::Error for BMP, ICO, PSD, SVG, JPEG XL, JPEG 2000, Netpbm and other formats – a breaking change for apps using those types
- Minimum supported versions are now libvips 8.13 and ruby‑vips 2.2.1; boot will raise a RuntimeError if not met
- The change fixes CVE‑2026‑66066, improving security; apps can re‑enable loaders in an initializer or remove ruby‑vips to avoid the breakage
