🚨 A sneaky stored XSS vulnerability in Dolibarr's WYSIWYG Editor allows low-privileged users to slip malicious scripts into private notes! 🔥 Think of it like a cafe where patrons can leave personal messages on napkins. If a lowly customer scribbles a nasty note that somehow gets read by the cafe's manager, chaos could ensue! If a victim opens their private notes, they could unwittingly trigger the script, which might snatch their session ID and pave the way for complete account takeover. Imagine a privileged admin being duped into revealing their credentials—absolutely devastating for your organization's security!
Think of it like a cafe where patrons can leave personal messages on napkins. If a lowly customer scribbles a nasty note that somehow gets read by the cafe's manager, chaos could ensue!
