Authenticated SSRF via uploadfile destination manipulation

Published Apr 19, 2026 · Updated Apr 19, 2026

SSRF in the PHPEMS 11.0 Instant Exam Creation Handler allows remote authenticated users to initiate server-side requests via uploadfile. Published records identify the temppage function in /app/exam/controller/exams.master.php but do not disclose the request API or exact validation failure. Low-privilege access is required, and the requests can target unintended destinations reachable from the PHPEMS server.
