🚨 A single sneaky script can put everything at risk! The WPO365 | LOGIN WordPress plugin is vulnerable to a persistent XSS flaw that could let attackers take control with just a clever payload. 🔥 Think of this vulnerability like a restaurant that stores a customer’s favorite dish alongside their order. If someone sneaks in a poisonous ingredient, every time that dish is served, it can make the next guest sick — allowing the attacker to wreak havoc with every serving! An attacker could exploit this flaw to hijack sessions, take over accounts, and access sensitive data. If they execute their payload successfully, they could run amok in the WordPress Dashboard, adding new admin users and changing crucial settings—essentially assuming full control of your site!
