CVE-2026-14749Public exploitNetwork attack vector

Unauthenticated PHP code execution via calculator eval

Published Jul 5, 2026 · Updated Jul 5, 2026

Code injection in mjperpinosa stumasy 327d1b0f2915ba79d7ef8ebb74553e987609d9be allows remote attackers to execute arbitrary PHP code. The unauthenticated calculate.php endpoint decodes the mathematical_sentence POST value as JSON and passes each nested value directly to eval() without validation. Code runs as the web server user and can read or write application data; operating-system command execution depends on enabled PHP functions.
