CVE-2026-7660 davidanderson CVE debrief
A reflected cross-site scripting (XSS) vulnerability exists in the Easy Updates Manager WordPress plugin, affecting versions up to and including 9.0.20. The flaw resides in the pagination() function, where insufficient input sanitization and output escaping of the 'paged' parameter allow attackers to inject arbitrary web scripts. Successful exploitation requires tricking an administrator into clicking a maliciously crafted link, causing the injected script to execute in the context of the administrator's browser session. The vulnerability was reported with a CVSS 3.1 score of 6.1 (Medium severity).

Who should care
WordPress site administrators using Easy Updates Manager plugin versions 9.0.20 or earlier; security teams monitoring plugin vulnerabilities; developers maintaining WordPress installations with administrative interfaces.
Technical summary
The vulnerability stems from improper handling of the 'paged' parameter in the pagination() function. The parameter value is not adequately sanitized before being output in HTML, enabling reflected XSS attacks. The attack vector is network-based, requires low attack complexity, no privileges, but does require user interaction (administrator clicking a link). The scope is changed due to the ability to affect components beyond the vulnerable module.
Defensive priority
