What it is

🚨 A crafty payload can transform a simple wiki page into a launchpad for malicious scripts! 🔥 Think of it like a restaurant where customers can write their own menu items. If nobody checks what's written, a prankster could sneak in a dish that causes chaos for everyone who orders it. With this vulnerability, an attacker could inject arbitrary web scripts or HTML into parent wiki pages, potentially leading to stolen credentials, session hijacking, or other devastating consequences. This is not just a prank; it can severely compromise the integrity of your site and the safety of your users!
