Authenticated PHP code execution via profile field eval

Published May 15, 2026 · Updated May 15, 2026

Code injection in ORSEE 3.1.0 allows remote authenticated users to execute arbitrary PHP code through participant profile fields. The participant and options tagset handlers pass func:-prefixed field values directly to eval() without neutralizing PHP syntax. An account able to modify affected profile fields can run code with the web application's server-side privileges.
