What is CVE-2023-0586?

The All in One SEO Pack plugin for WordPress exhibits a vulnerability that allows authenticated attackers with Contributor or higher roles to exploit stored Cross-Site Scripting (XSS). This vulnerability arises from inadequate input sanitization and output escaping across multiple input parameters, enabling attackers to inject arbitrary web scripts into pages. These scripts are executed whenever a user visits the compromised pages, risking the integrity of the user session and potentially leading to further attacks.
