SCA: security update for yiisoft/yii2-authclient (GHSA-rw54-6826-c8j5)

high Tenable Cloud Security Plugin ID 418954

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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 Oauth2 PKCE implementation is vulnerable in
 2 ways. First, the `authCodeVerifier` should be removed after usage (similar to `authState`). Second,
 there is a risk for a `downgrade attack` if PKCE is being relied on for CSRF protection. Version 2.2.15
 contains a patch for the issue. No known workarounds are available. (CVE-2023-50714)
