What is CVE-2023-50708?

yii2-authclient is an extension that adds OpenID, OAuth, OAuth2 and OpenId Connect consumers for the Yii framework 2.0. In yii2-authclient prior to version 2.2.15, the Oauth1/2 state and OpenID Connect nonce is vulnerable for a timing attack since it is compared via regular string comparison (instead of Yii::$app->getSecurity()->compareString()). Version 2.2.15 contains a patch for the issue. No known workarounds are available.

Affected Version(s)

yii2-authclient < 2.2.15
