An argument injection vulnerability in the Dragonfly gem before 1.4.0 for Ruby allows remote attackers to read and write to arbitrary files via a crafted URL when the verify_url option is disabled. This may lead to code execution. The problem occurs because the generate and process features mishandle use of the ImageMagick convert utility.
Affected configurations
| CPE | Name | Operator | Version |
|---|---|---|---|
| dragonfly_project:dragonfly | dragonfly project dragonfly | lt | 1.4.0 |
