Summary
Yii 2 Redis may expose AUTH parameters in logs in case of connection failure
Impact
On failing connection extension writes commands sequence to logs. AUTH parameters are written in plain text exposing username and password. That might be an issue if attacker has access to logs.
Affected versions
Security releases
Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.

- What is CVE-2025-48493? CVE-2025-48493 is a medium-severity security vulnerability in yiisoft/yii2-redis (composer), affecting versions < 2.0.20. It is fixed in 2.0.20.
- Which versions of yiisoft/yii2-redis are affected by CVE-2025-48493? yiisoft/yii2-redis (composer) versions < 2.0.20 is affected.
- Is there a fix for CVE-2025-48493? Yes. CVE-2025-48493 is fixed in 2.0.20. Upgrade to this version or later.
- Is CVE-2025-48493 exploitable, and should I be worried? Whether CVE-2025-48493 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

- What actually determines whether CVE-2025-48493 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
