CVE-2026-15559Public exploitNetwork attack vector

Authenticated SQL injection via unsanitized appid parameter

Published Jul 13, 2026 · Updated Jul 13, 2026

SQL injection in CodeAstro Simple Online Leave Management System 1.0 allows remote authenticated users to execute SQL via a POST request. The accept.php handler directly inserts the appid POST parameter into a database query without validation, sanitization, or parameter binding. The admin endpoint requires an authenticated session; the demonstrated time-based blind payload discloses database contents through response delays, while injected statements operate within the application's database privileges.
