Overview
Affected versions of this package are vulnerable to Arbitrary File Upload due to improper validation of file extensions. An attacker can bypass SVG file sanitization protections by initially uploading a file with a permitted extension and subsequently renaming it to an .svg extension.
Note:
This is only exploitable if the media.clean_vectors configuration is enabled and the attacker has administrative access.
