Input validation vulnerability in Nexa Blocks – Gutenberg Blocks, Page Builder for Gutenberg Editor & FSE 1.1.0

The Nexa Blocks plugin for WordPress has a security issue called Stored Cross-Site Scripting. This can happen when using the plugin’s Google Maps feature on any version up to 1.1.0. The problem is that the plugin does not properly clean up or protect the information that users input. This means that someone with contributor-level access or higher can insert harmful web scripts into pages. These scripts will then run whenever someone visits that page.
