CyberChimps Responsive Blocks can let attackers run code

CVE-2025-53202 · published 1 year ago
Summary

The Responsive Blocks add‑on for CyberChimps websites does not properly clean user input when it builds pages, allowing a type of attack called DOM‑based cross‑site scripting. An attacker could inject malicious script that runs in a visitor’s browser, potentially stealing data or altering the page. Update the add‑on to version 2.0.7 or later, or remove it if you cannot apply the update, and ensure any custom code also validates input.
