commitment

# **Organizations should inventory Brotli versions in Node.js, Bun, Envoy, Istio and Python environments, since updating the runtime is not always sufficient and separate Brotli libraries inside the application should also be checked.**

A commitment by Turan Security Xavfsizlik Byulleteni. Statements are as reported by the cited publishers — not verified by DecisionGateway.

> *Node.js, Bun, Envoy, Istio va Python muhitlaridagi Brotli versiyalarini inventarizatsiya qiling - runtime'ni yangilash har doim ham yetarli emas, ilova ichidagi alohida Brotli kutubxonalarini ham tekshiring.*
