**Name of the Vulnerable Software and Affected Versions** yiisoft/yii versions prior to 1.1.29 **Description** The issue allows for Remote Code Execution (RCE) if the application calls `unserialize()` on arbitrary user input. An attacker may leverage this to compromise the host system. **Recommendations** For versions prior to 1.1.29, upgrade to version 1.1.29 or higher. As a temporary workaround, consider avoiding the use of `unserialize()` on arbitrary user input until the issue is resolved. Restrict access to sensitive areas of the application to minimize the risk of exploitation.
