Authenticated arbitrary file upload via profile update

Published Aug 21, 2026 · Updated Aug 21, 2026

Unrestricted file upload in CodeAstro Online Job Portal 1.0 allows remote authenticated users to upload arbitrary files via profile updates. The /users/update-profile.php handler accepts a file supplied through the Name argument without restricting the upload to safe file types. Low-privilege authenticated access is required, and public evidence does not establish that an uploaded file can execute on the server.
