What it is

⚠️ Sensitive data is just lying around waiting to be picked up! The Nexter Blocks plugin version 4.6.3 and below exposes embedded information—just like leaving your diary open on a park bench. 📖✨ Think of it as a restaurant that accidentally leaves the kitchen door open, allowing anyone to peek at the secret recipe book. If someone strolls by—bam!—they could snag all the juicy details without breaking a sweat. An unauthorized user could potentially retrieve sensitive system information, leading to privacy concerns and the risk of further exploitation. While this isn’t the end of the world, it’s definitely a medium-risk situation that needs addressing before it spirals out of control!
