What is CVE-2026-10551?

The Breeze Cache plugin for WordPress is susceptible to unauthenticated Stored Cross-Site Scripting (XSS).

As a result, attackers can inject arbitrary HTML attributes into the final HTML output by guessing the placeholder format, potentially compromising site security and user data.
