IBM Observability with Instana (Agent) Build 1.0.303 through 1.0.320 IBM Instana Node.js tracer component @instana/core version 6.2.1 is vulnerable to prototype pollution through its configuration normalization API.

The OpenTelemetry.Exporter.Instana exports telemetry to Instana backend. Prior to 1.1.0, the OpenTelemetry.Exporter.Instana NuGet package does not validate HTTPS/TLS certificates are valid when sending telemetry to a configured Instana back-end when a proxy is configured using the INSTANA_ENDPOINT_PROXY environment variable. If a network attacker can Man-in-the-Middle (MitM) the proxy connection, all OpenTelemetry telemetry data and the Instana API key are exposed to the attacker. This vulnerability is fixed in 1.1.0.

IBM Observability with Instana 1.0.243 through 1.0.254 could allow an attacker on the network to execute arbitrary code on the host after a successful DNS poisoning attack. IBM X-Force ID: 259789.
