Recommendation: Plan a near-term fix — a public PoC already exists.

Redaxo CMS Mediapool Addon 5.5.1 and older contains an arbitrary file upload vulnerability that allows authenticated users to bypass file extension blacklist restrictions. Attackers with editor accounts can upload executable files by using obfuscated extensions like php71 or php53 to evade the blacklist filter and execute arbitrary code.
