Description

An insecure deserialization vulnerability exists in the rss-mp3.php script of the MiczFlor RPi-Jukebox-RFID project through commit 4b2334f0ae0e87c0568876fc41c48c38aa9a7014 (2025-10-07). The 'rss' GET parameter receives data that is passed directly to the unserialize() function without validation. This allows a remote, unauthenticated attacker to inject arbitrary PHP objects, causing the application to process them and leading to errors or a denial of service.
