Yii 2 Redis may expose AUTH paramters in logs in case of connection failure

Published Jun 5, 2025 CVSS 4.0 · 5.1 Medium EPSS < 1% KEV · Not listed

Description

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.
