CVE-2026-14777Public exploitNetwork attack vector

Authenticated code execution via unchecked attachment upload

Published Jul 5, 2026 · Updated Jul 5, 2026

Unrestricted file upload in SourceCodester Online Examination LMS 1.0 allows remote authenticated users to execute commands via attachments. The announcements.php handler preserves the attachment extension and calls move_uploaded_file without checking its extension, MIME type, or content, placing the result in a PHP-enabled web directory. Clerk or super-admin access is required; an uploaded PHP web shell executes commands under the web server account.
