What it is

⚠️ Who knew a tiny parameter could open the door to chaos? The `deleteBackup` parameter in Bludit v3.13.0 allows arbitrary file deletion — like a waiter accidentally tossing your order into the trash! It's like a restaurant where the kitchen staff is allowed to throw away any dish simply by saying, "Delete that order!" without verifying if it’s even part of their station. One wrong command could mean losing critical data without any checks. An attacker exploiting this vulnerability could delete essential backup files, leaving your site vulnerable and potentially requiring hours of reconstruction work. Imagine the panic of recreating lost data from scratch — absolutely devastating!
