CVE-2026-10551: Unknown Breeze Cache

Medium severity, CVSS 6.1. EPSS: 0.3% chance of exploitation in the next 30 days.

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.

Affected products

• Unknown Breeze Cache: before 2.5.6 (fixed in 2.5.6)
