⚠️ Remote attackers can sneak commands right into your forum with a crafty use of shell metacharacters in the topic hidden field! Imagine a hotel lobby where guests can slip secret notes to the staff without anyone noticing — that’s how shell metacharacters operate here, allowing attackers to send commands disguised as innocent topics! An attacker could exploit this vulnerability to run arbitrary commands on your server, potentially gaining control over the entire system. Picture someone sneaking in and altering your guest book, taking control of reservations, and even locking you out of your own hotel!
