Kyverno Denial of Service via Context Variable Amplification in Policy Engine
Kyverno is a policy engine designed for cloud native platform engineering teams. Versions prior to 1.16.3 and 1.15.3 have unbounded memory consumption in Kyverno's policy engine that allows users with policy creation privileges to cause denial of service by crafting policies that exponentially amplify string data through context variables. Versions 1.16.3 and 1.15.3 contain a patch for the vulnerability.
