Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects Packagist packages — download data is not available via public APIs for these ecosystems.

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.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for yiisoft/yii2-redis, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update yiisoft/yii2-redis to 2.0.20 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2025-48493 is resolved across your whole dependency graph.

  3. Workarounds

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
