In yiisoft/yii2 version 2.0.48, the base Component class contains a vulnerability where the set() magic method does not validate that the value passed is a valid Behavior class name or configuration. This allows an attacker to instantiate arbitrary classes, passing parameters to their constructors and invoking setter methods. Depending on the installed dependencies, various types of attacks are possible, including the execution of arbitrary code, retrieval of sensitive information, and unauthorized access.

Impact Affected versions of yiisoft/yii are vulnerable to Reflected XSS in specific scenarios where the fallback error renderer is used.

Patches Upgrade yiisoft/yii to version 1.1.31 or higher.

An XSS vulnerability exists in framework/views/errorHandler/exception.php in Yii Framework 2.0.12 affecting the exception screen when debug mode is enabled, because $exception->errorInfo is mishandled.

DISPUTED Yii 2 v2.0.45 was discovered to contain a cross-site scripting (XSS) vulnerability via the endpoint /books. NOTE: this is disputed by the vendor because the cve-2022-31454-8e8555c31fd3 page does not describe why /books has a relationship to Yii 2.

Yii 2.x through 2.0.15.1 actively converts a wildcard CORS policy into reflecting an arbitrary Origin header value, which is incompatible with the CORS security design, and could lead to CORS misconfiguration security problems.
