CVE-2025-12862Public exploitNetwork attack vector

Authenticated code execution via unvalidated profile image upload

Published Nov 7, 2025 · Updated Nov 7, 2025

Unrestricted file upload in Projectworlds Online Notes Sharing Platform 1.0 allows remote authenticated users to execute PHP code. The userprofile.php profile-photo handler uses the image field from $_FILES to choose a web-accessible storage path without validating the extension, MIME type, content, or filename. A valid user session is required; a multipart upload labeled image/jpeg can carry a .php file whose later web request runs commands under the web server account.
