# CVE-2025-47916: invisioncommunity Invision Power Board

- Exploited (CISA KEV): no
- Published: 2025-05-16
- CVSS: 10 CRITICAL (v3.1)
- EPSS: 84.3% (100th percentile)
- CWE: CWE-1336

Invision Community 5.0.0 before 5.0.7 allows remote code execution via crafted template strings to themeeditor.php. The issue lies within the themeeditor controller (file: /applications/core/modules/front/system/themeeditor.php), where a protected method named customCss can be invoked by unauthenticated users. This method passes the value of the content parameter to the Theme::makeProcessFunction() method; hence it is evaluated by the template engine. Accordingly, this can be exploited by unauthenticated attackers to inject and execute arbitrary PHP code by providing crafted template strings.
