## Technical details

The weDocs plugin for WordPress is vulnerable to Stored Cross-Site Scripting (XSS) due to insufficient input sanitization and output escaping on the 'connectorWidth' block attribute within the Sidebar component. An authenticated attacker with contributor-level permissions or higher can inject arbitrary web scripts into a page. Because the payload is stored in the database, the script executes in the context of any user's browser who views the compromised page. This vulnerability is tracked as CWE-79 and affects all versions up to and including 2.3.0. A patch has been released in subsequent versions to address the improper neutralization of input.
