CyberRota Analysis

AI-Generated

The EONSR AEO Agent WordPress plugin versions up to 3.7.9 lacks proper authorization checks on a REST API route and fails to sanitize HTML before saving posts. This vulnerability allows unauthenticated attackers to publish posts with arbitrary web scripts, leading to stored cross-site scripting (XSS) that can execute in the browsers of all visitors, including administrators. WordPress site administrators using this plugin should prioritize immediate updates to mitigate potential exploitation.
