Authenticated message spoofing via origin-authentication bypass
Published Jun 17, 2026 · Updated Jun 17, 2026
Authentication bypass in RTI Connext Professional Security Plugins allows remote authenticated users to publish spoofed messages. RTPS origin authentication accepts messages from one authenticated participant as if they originated from another participant. Exploitation requires both participants in the same domain and prior authentication by the participant being impersonated, enabling unauthorized publication.
