Input validation vulnerability in Crypto Converter ⚡ Widget 1.8.1

The Crypto Converter Widget plugin for WordPress is vulnerable to a type of attack called Stored Cross-Site Scripting. This attack can allow malicious users with contributor-level access or higher to insert malicious code on webpages. This malicious code will then be executed whenever someone visits the page. In order to protect against this attack, the plugin needs to be updated to version 1.8.1 or higher, as earlier versions do not have proper safeguards in place.
