Unauthorized connections via revoked permission grant acceptance
Published Dec 23, 2025 · Updated Dec 23, 2025
Certificate validation bypass in eProsima Fast DDS 3.3.0 allows remote attackers to establish unauthorized secure connections. The access-control path accepts a permission grant when is_validation_in_time finds its time window current, without rechecking whether the grant has been revoked. Exploitation requires network reachability to a security-enabled DDS domain and a previously valid but revoked grant, enabling unauthorized data exchange without interrupting the service.
