## Description

# Active Storage allowed transformation methods potentially unsafe
Active Storage attempts to prevent the use of potentially unsafe image
transformation methods and parameters by default.
The default allowed list contains three methods allow for the circumvention
of the safe defaults which enables potential command injection
vulnerabilities in cases where arbitrary user supplied input is accepted as
valid transformation methods or parameters.
Impact
------
This vulnerability impacts applications that use Active Storage with the
image\_processing processing gem in addition to mini\_magick as the image
processor.
Vulnerable code will look something similar to this:
```
<%= image\_tag blob.variant(params[:t] => params[:v]) %>
```
Where the transformation method or its arguments are untrusted arbitrary
input.
All users running an affected release should either upgrade or use one of
the workarounds immediately.
Workarounds
-----------
Consuming user supplied input for image transformation methods or their
parameters is unsupported behavior and should be considered dangerous.
Strict validation of user supplied methods and parameters should be
performed
as well as having a strong [ImageMagick security
policy](https://imagemagick.org/script/security-policy.php) deployed.
