CVE-2025-55743Public exploitNetwork attack vector

Authenticated code execution via executable image upload

Published Aug 21, 2025 · Updated Aug 21, 2025

Unrestricted file upload in Bagisto UnoPim before 0.2.1 allows remote authenticated users to execute arbitrary PHP via a user image. The user-creation image handler relies on client-side file checks, so a modified multipart request stores PHP content under an executable filename. Access to the administrator user-creation function is required; requesting the uploaded file provides server-side command execution.
