Security readout for executives and security teams
Yii Framework versions before 2.0.4 had an XSS flaw that could allow injected script or HTML in certain JSON, array, and legacy Internet Explorer handling paths. Business risk is mainly to web applications still running old Yii 2 code. The supplied sources do not show active exploitation. Exposure is likely limited to public or internal web applications built on Yii Framework 2.x older than 2.0.4. Systems not using Yii 2, or already running 2.0.4 or later, are not indicated as affected by the provided sources. Treat this as a cleanup priority for legacy Yii applications, especially internet-facing ones. It is not evidenced as actively exploited in the supplied sources, but XSS can still affect user trust, sessions, and data integrity when reachable. Mitigation focus: Upgrade Yii Framework to 2.0.4 or later where feasible.; Review Yii 2.0.4 release notes and changelog for vendor-fixed behavior.; Check vendor guidance if an immediate framework upgrade is not possible..
