CVE-2025-14834Public exploitNetwork attack vector

Database compromise via injectable username query

Published Dec 17, 2025 · Updated Dec 17, 2025

SQL injection in /market/checkuser.php in Code Projects Simple Stock System 1.0 allows remote authenticated users to compromise database data. The endpoint treats the username GET parameter as SQL syntax, letting a quote and Boolean expression alter the user lookup query. A low-privilege session is required; the published proof of concept demonstrates authentication bypass and supports database data exfiltration.
