Last modified
CVE-2026-122006 is a critical-severity vulnerability rated 9.8/10 on the CVSS scale. The activestorage gem before 8.1.4.1 for Ruby on Rails, when ImageMagick attachment processing occurs, can allow server read and write operations (e.g., reading secret_key_base) because the ImageMagick analyzer runs when a file is attached, and there is not an ImageMagick security policy to block unintended functionality.. EPSS estimates a 0.69% chance of exploitation in the next 30 days.
