Improper Authentication

Akka.NET is vulnerable to improper authentication. The vulnerability is due to the lack of mutual TLS enforcement in Akka.Remote, which allows an attacker to connect to a TLS-enabled cluster without presenting a valid client certificate and thereby communicate with the cluster...

GHSA-JHPV-4Q4F-43G5 Akka.Remote TLS did not properly implement certificate-based authentication

Impact This is a critical network security vulnerability for Akka.Remote users who have SSL / TLS enabled on their Akka.Remote connections and were expecting certificate-based authentication to be enforced on all peers attempting to join the network. In all versions of Akka.Remote from v1.2.0 to...

CVE-2025-61778

Akka.NET is a .NET port of the Akka project from the Scala / Java community. In all versions of Akka.Remote from v1.2.0 to v1.5.51, TLS could be enabled via our akka.remote.dot-netty.tcp transport and this would correctly enforce private key validation on the server-side of inbound connections...

User Impersonation

Overview Akka.Remote is a .NET port of the popular Akka project from the Scala / Java community. Affected versions of this package are vulnerable to User Impersonation due to improper implementation of certificate-based authentication in the akka.remote.dot-netty.tcp transport. An attacker can ga...

Insecure Random Number Generation

akka-remote is vulnerable to insecure random number generation. When a custom random number generator is configured, if the AES128CounterSecureRNG and AES256CounterSecureRNG are enabled, a malicious user can easily guess the random number used during encryption and possibly eavesdrop onto ongoing...
