Vulnerability Overview
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.
Technical Analysis
The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site.
CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Easy Updates Manager <= 9.0.20 carries this weakness at paged, and reaching it takes a caller who can reach the endpoint. Cross-site scripting happens when input from a request is written into a page without being escaped for the context it lands in, so the browser parses attacker-supplied text as markup or script.
Injected script runs with the privileges of whoever views the affected page, which is how these flaws turn into administrator session theft, silent account creation or persistent backdoors in page content. For Easy Updates Manager the fix is 9.0.21: builds <= 9.0.20 are affected, anything from 9.0.21 onward is not.
Remediation
Update to version 9.0.21, or a newer patched version
