Summary
The Smart Popup by Supsystic WordPress plugin before 2.0.2 does not prevent template-injection payloads from being stored in a popup text block and later evaluated by its template engine. The filter meant to strip template delimiters runs before a decoding step that reconstructs them, allowing an authenticated administrator to execute arbitrary template expressions server-side and read PHP constants such as the site's database credentials and authentication keys.
Risk Assessment
A site administrator can exploit the flaw to read sensitive data, including database credentials and authentication keys, potentially leading to full site compromise. The risk mainly affects environments where administrator accounts may be compromised or where multiple administrators with limited trust exist.
Recommendation
Update the Smart Popup by Supsystic plugin to version 2.0.2 or later. Additionally, limit the number of administrator accounts and regularly rotate keys and access credentials.

The Smart Popup by Supsystic WordPress plugin before 2.0.2 does not prevent template-injection payloads from being stored in a popup text block and later evaluated by its template engine, because the filter meant to strip template delimiters runs before a decoding step that reconstructs them, allowing an authenticated administrator to execute arbitrary template expressions server-side and read PHP constants such as the site's database credentials and authentication keys.
