This security flaw was discovered and publicly disclosed on January 17, 2022, allowing unauthenticated users to perform Denial of Service attacks on WordPress blogs using the affected plugin (WPScan).

Technical details

The vulnerability stems from the plugin's functionality where it autoloads popup data on every page.

This implementation flaw is classified under CWE-400 (Uncontrolled Resource Consumption) (NVD Report).

Impact

When exploited, this vulnerability can cause a Denial of Service condition on the affected WordPress blog. Since the malicious data is loaded at each page view, it can significantly impact the website's performance and availability (WPScan).

Mitigation and workarounds

The vulnerability has been fixed in version 1.3.1 of the Popup | Custom Popup Builder plugin. Website administrators running affected versions should update to version 1.3.1 or later to mitigate this security risk (WPScan).
