CVE-2026-19998Public exploitNetwork attack vector

Script execution via unsanitized email reflection

Published Aug 17, 2026 · Updated Aug 18, 2026

Cross-site scripting in offersmail.php in Code Projects Online Shopping System 1.0 allows remote attackers to execute script via email input. When email validation fails, offersmail.php echoes the POSTed email value into a warning message with no HTML encoding or sanitization, so injected tags are reflected back and executed by the browser. No authentication is required, but successful exploitation depends on reaching the error path with a crafted invalid email value and affects only the victim browser session.
