Vulnerability Title
CP Multi View Events Calendar <= 1.4.42 - Unauthenticated Stored Cross-Site Scripting via 'CalendarTitle' Parameter
Source: CVE Program / CVE List V5
Vulnerability Description
The CP Multi View Events Calendar plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'CalendarTitle' parameter in all versions up to, and including, 1.4.42 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This requires that an administrator has enabled the "Allow edition in frontend?" option on at least one calendar view, which exposes the unauthenticated add endpoint and a publicly accessible nonce.
