Yii 2 Redis may expose AUTH paramters in logs in case of connection failure
The Yii 2 Redis extension provides the redis key-value store support for the Yii framework 2.0. On failing connection, the extension writes commands sequence to logs. Prior to version 2.0.20, AUTH parameters are written in plain text exposing username and password. That might be an issue if attacker has access to logs. Version 2.0.20 fixes the issue.
Yii 2.x before 2.0.15 allows remote attackers to execute arbitrary LUA code via a variant of the CVE-2018-7269 attack in conjunction with the Redis extension.
