Details
There is a possible code injection vulnerability in the Active Storage module of Rails. This vulnerability has been assigned the CVE identifier CVE-2022-21831. Versions Affected: >= 5.2.0 Not affected: < 5.2.0 Fixed Versions: 7.0.2.3, 6.1.4.7, 6.0.4.7, 5.2.6.3 Impact ------ There is a possible code injection vulnerability in the Active Storage module of Rails. This vulnerability impacts applications that use Active Storage with the image_processing processing in addition to the mini_magick back end for image_processing. Vulnerable code will look something similar to this: ```ruby <%= 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 ----------- To work around this issue, applications should implement a strict allow-list on accepted transformation methods or arguments. Additionally, a strict image magick security policy will help mitigate this issue. https://imagemagick.org/script/security-policy.php
