Hi,

The following vulnerability was published for ruby-carrierwave.

CVE-2021-21305[0]:
| CarrierWave is an open-source RubyGem which provides a simple and
| flexible way to upload files from Ruby applications. In CarrierWave
| before versions 1.3.2 and 2.1.1, there is a code injection
| vulnerability. The "#manipulate!" method inappropriately evals the
| content of mutation option(:read/:write), allowing attackers to craft
| a string that can be executed as a Ruby code. If an application
| developer supplies untrusted inputs to the option, it will lead to
| remote code execution(RCE). This is fixed in versions 1.3.2 and 2.1.1.


If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
