Flaw Demands Immediate Patching","A critical vulnerability in Rails' Active Storage component (CVE-2026-66066) allows unauthenticated attackers to read arbitrary files and potentially execute remote code when the libvips image processing library is in use. The root cause lies in insufficient input validation within the image processing pipeline, enabling attackers to manipulate file paths or processing parameters maliciously. Exposure of sensitive credentials such as 'secret_key_base' can lead to full application compromise, session forgery, and cascading breaches. This flaw is especially dangerous because it requires no authentication, dramatically lowering the barrier for exploitation.
