CVE-2026-90857Network attack vector

Authenticated arbitrary file upload via profile image

Published Sep 15, 2026 · Updated Sep 15, 2026

Unrestricted file upload in SourceCodester College Notes Gallery Management System 1.0 allows remote authenticated users to upload arbitrary files. The image handler in /dashboard/userprofile.php accepts attacker-controlled profile-upload content without enforcing a safe file-type restriction. A valid user session is required; the demonstrated consequence is placement of an attacker-chosen file on the web server, while code execution is not established.
