Upgrade limesurvey/limesurvey to version 7.0.1 or higher.
Overview
limesurvey/limesurvey is a FOSS online survey tool on the web.
Affected versions of this package are vulnerable to SQL Injection via the invite_participants and remind_participants API methods, which pass user-supplied token-ID arrays directly into SQL queries without parameterization or input validation. An attacker with the appropriate permission can execute arbitrary SQL commands by injecting crafted input, potentially reading sensitive data such as administrator password hashes, survey responses, and session records, or modifying and deleting database contents. This is only exploitable if the RemoteControl interface (RPCInterface = json/xml) is enabled.
