🚨 A single script stored in a form field can turn an innocuous page into a playground for attackers! 🔥 Think of it like a recipe book at a restaurant where anyone with access can scribble in their own ingredients. A malicious contributor could add harmful instructions, and when the chef follows that recipe, diners are in for a nasty surprise! With this stored XSS vulnerability, an attacker could execute arbitrary scripts in the victim's browser, potentially stealing sensitive data or hijacking sessions. It's absolutely devastating as it allows attackers to manipulate the trust of users who think they're interacting with a legitimate form. If your organization uses affected versions, you're leaving the door wide open for mischief!
Think of it like a recipe book at a restaurant where anyone with access can scribble in their own ingredients. A malicious contributor could add harmful instructions, and when the chef follows that recipe, diners are in for a nasty surprise! This stored XSS flaw in AEM forms for versions 6.5.5.0 (and below) and 6.4.8.2 (and below) lets users with 'Author' privileges inject scripts into form fields, which will execute when a victim loads the page containing those fields.
