description
ASP.NET Core applications using the SignalR StackExchange Redis scale-out component are affected. An unauthenticated network attacker may cause retained group subscriptions to consume resources and disrupt service when the affected SignalR Redis integration is exposed.
mitigation
Update Microsoft.AspNetCore.SignalR.StackExchangeRedis and affected ASP.NET Core runtime packages to 8.0.34, 9.0.23, 10.0.15, or 11.0.0, as appropriate for the application’s release line. Prioritize internet-accessible applications using SignalR Redis scale-out.
fixed in 8.0.34, 9.0.23, 10.0.15, 11.0.0
