**Name of the Vulnerable Software and Affected Versions**
HorizontCMS version 1.0.0-beta
**Description**
The issue allows an authenticated remote attacker to upload PHP code through a zip file by uploading a theme. The attacker can then execute the PHP file via an HTTP GET request to /themes/<php file name>.
**Recommendations**
For HorizontCMS version 1.0.0-beta, consider restricting access to the theme upload feature to prevent unauthorized file uploads until a patch is available. As a temporary workaround, restrict access to the /themes/ directory to minimize the risk of exploitation.
