CVE-2020-15148: Deserialization of Untrusted Data

September 15, 2020 (updated January 7, 2021)

Yii 2 (yiisoft/yii2) before version 2.0.38 is vulnerable to remote code execution if the application calls unserialize() on arbitrary user input. This is fixed in version 2.0.38. A possible workaround without upgrading is available in the linked advisory.
