- CISA SSVC: exploitation=poc, automatable=no, technicalImpact=total

## Affected

- Glossword Team Glossword: from 1.8.8, through 1.8.12

## Description

Glossword versions 1.8.8 through 1.8.12 contain an authenticated arbitrary file upload vulnerability. When deployed as a standalone application, the administrative interface (gw_admin.php) allows users with administrator privileges to upload files to the gw_temp/a/ directory. Due to insufficient validation of file type and path, attackers can upload and execute PHP payloads, resulting in remote code execution.
