Description
Joomla Extension - joomshaper.com - Stored Cross-Site Scripting (XSS) in MegaMenu Layout Container & Embed Inputs in Helix Ultimate < 2.2.11 - Unsanitized column and item configuration values stored within the MegaMenu layout JSON were rendered without complete contextual escaping, allowing injection of malicious HTML/JS. Stricter sanitization and tag allowlists via `InputFilter` and `htmlspecialchars` were implemented.
