What it is

⚡ A sneaky stored XSS vulnerability has been discovered in OnboardLite, affecting the admin dashboard when migrating Discord accounts! 🔥 Think of it like a restaurant where the chef has to trust that the delivery person isn’t carrying a poisoned dish. If the admin isn’t careful, they might serve up malicious code instead of a seamless user experience! If exploited, this vulnerability could allow an attacker to inject harmful scripts that execute within the admin’s browser session. This could lead to data theft, unauthorized actions, or even complete takeover of the account, all while the admin is blissfully unaware. Essentially, it transforms the migration process into a dangerous endeavor!

Think of it like a restaurant where the chef has to trust that the delivery person isn’t carrying a poisoned dish. If the admin isn’t careful, they might serve up malicious code instead of a seamless user experience! This stored cross-site scripting (XSS) vulnerability allows malicious users to craft scripts that are stored on the server and executed in the context of the admin's session when they attempt to migrate a user's Discord account. The flaw resides in versions before commit 1d32081a66f21bcf41df1ecb672490b13f6e429f.
