A vulnerability has been identified in Industrial Edge App Publisher (All versions < V1.27.9). The affected software does not properly validate the server certificate when initiating a TLS connection. This allows an attacker to intercept and relay communication (Man-in-the-Middle attack) and to spoof a trusted entity by interfering in the communication path between the client and the intended server.
