CVE-2022-24720: Prevent remote shell execution in `#apply` · janko/image_processing@038e457
image_processing is an image processing wrapper for libvips and ImageMagick/GraphicsMagick. Prior to version 1.12.2, using the #apply method from image_processing to apply a series of operations that are coming from unsanitized user input allows the attacker to execute shell commands. This method is called internally by Active Storage variants, so Active Storage is vulnerable as well. The vulnerability has been fixed in version 1.12.2 of image_processing. As a workaround, users who process based on user input should always sanitize the user input by allowing only a constrained set of operations.
