## Summary

The Smart Popup plugin by Supsystic for WordPress is affected. An authenticated administrator can inject template code into a popup text block that the server then runs, which can expose sensitive site settings such as database credentials and authentication keys.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Affected

- Unknown Smart Popup by Supsystic: fixed in 2.0.2

## Description

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.
