CVE-2026-6489Public exploitNetwork attack vector

Authenticated code execution via unchecked image upload

Published Apr 17, 2026 · Updated Apr 17, 2026

Unrestricted file upload in QueryMine sms at commit 7ab5a9ea196209611134525ffc18de25c57d9593 allows remote authenticated users to execute PHP code. The admin/addteacher.php handler copies the image upload's attacker-controlled original filename into the Web-accessible img directory without checking its extension, MIME type, or contents. A valid background-management session is required; uploading a PHP script and requesting the stored file executes code with the Web server process's privileges.
