**Name of the Vulnerable Software and Affected Versions** Symphony CMS versions prior to 2.6.12 **Description** A Remote Code Execution issue allows remote attackers to execute code and obtain a webshell from the back-end. The attacker must be authenticated and enter PHP code in the `datasource` editor or `event` editor. **Recommendations** For versions prior to 2.6.12, update to version 2.6.12 or later to resolve the issue. As a temporary workaround, consider restricting access to the `datasource` editor and `event` editor to minimize the risk of exploitation.
