What is CVE-2026-13701?
The Advanced Excerpt plugin for WordPress, prior to version 4.5, contains a vulnerability that fails to properly sanitize and escape a specific setting before rendering it on the front end. This oversight can potentially allow administrators, including those without the unfiltered_html capability in multisite setups, to launch Stored Cross-Site Scripting (XSS) attacks. Such attacks can execute malicious scripts in the browser of any visitor who views the compromised pages, leading to unauthorized actions and data exposure.
