CVE-2023-50708

yii2-authclient is an extension that adds OpenID, OAuth, OAuth2 and OpenId Connect consumers for the Yii framework 2.0.

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.
