## Affected

## Description

Camaleon CMS before 2.9.3 contains a path traversal vulnerability that allows users with only the media permission to write arbitrary files by supplying ../ sequences in the name parameter. Attackers can send a base64 data: URI to the crop_url media action to write an ERB template into a theme's views directory, which executes when rendered.
