The EONSR AEO Agent WordPress plugin through 3.7.9 does not perform any authorisation check on one of its REST API routes and disables HTML sanitisation before saving the post, allowing unauthenticated attackers to create administrator-attributed published posts containing arbitrary web scripts that execute in the browser of any visitor, including administrators (Stored XSS).
