Login by Auth0 <= 4.6.0 - Reflected Cross-Site Scripting via wle

The Login by Auth0 plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the ‘wle’ parameter in all versions up to, and including, 4.6.0 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.

An issue was discovered in the Login by Auth0 plugin before 4.0.0 for WordPress. A user can perform an insecure direct object reference.

An issue was discovered in the Login by Auth0 plugin before 4.0.0 for WordPress. It has numerous fields that can contain data that is pulled from different sources.

This can lead to (at least) CSV injection if a crafted Excel document is uploaded.
