The Easy Updates Manager plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'paged' parameter in versions up to, and including, 9.0.20 This is due to insufficient input sanitization and output escaping in the pagination() function. This makes it possible for attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page granted they can trick an administrator into performing an action such as clicking on a link.
