Remote shell execution vulnerability in image_processing
Impact
When using the #apply method from image_processing to apply a series of operations that are coming from unsanitized user input, this allows the attacker to execute shell commands:
This method is called internally by Active Storage variants, so Active Storage is vulnerable as well.
Patches
The vulnerability has been fixed in version 1.12.2 of image_processing.
Workarounds
If you're processing based on user input, it's highly recommended that you always sanitize the user input, by allowing only a constrained set of operations. For example:

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.
