Critical (9.3). EPSS 2.1% chance of exploitation in the next 30 days.
An unauthenticated arbitrary file upload vulnerability exists in FlashChat versions 6.0.2 and 6.0.4 through 6.0.8. The upload.php endpoint fails to properly validate file types and authentication, allowing attackers to upload malicious PHP scripts. Once uploaded, these scripts can be executed remotely, resulting in arbitrary code execution as the web server user.
