CVE-2026-10551

MEDIUM 6.1 PoC AVAILABLE

Published 2026-07-13 · Last modified 2026-07-13

The Breeze Cache WordPress plugin before 2.5.6 is vulnerable to unauthenticated Stored Cross-Site Scripting (XSS) due to a predictable replacement hash used during the HTML minification process and abusing a regular expression. This allows an attacker to inject arbitrary HTML attributes in the final HTML output by anticipating the placeholder format.
