🚨 A crafty PHP file is all it takes! The is_allowed_file_type() function in Filemanager v2.3.0 has a serious flaw that lets attackers upload malicious files — it’s like inviting someone in for tea and they turn out to be a burglar! 🔥 Think of a restaurant where the chef accepts any dish sent through the back door without even looking at it. That’s how this function operates, allowing harmful files into the system without proper checks! An attacker could gain full control of the server by executing their own code, leading to devastating data breaches, unauthorized access, and potentially wreaking havoc on your entire infrastructure. This could expose sensitive information or compromise your application in unimaginable ways!
