CVE-2026-112331: Improper Handling of Exceptional Conditions in GDATASoftwareAG motornet
Description
Motor.NET versions before 0.19.0 have a denial-of-service vulnerability. A remote attacker can crash the service permanently by sending a crafted record with a specific content-type header and missing required CloudEvent attributes. This triggers a fatal exception causing the service to enter a crash-loop on restart.

Technical Analysis
Motor.NET before version 0.19.0 contains a denial-of-service vulnerability where a remote attacker who can produce records to a consumed topic can cause a permanent crash. By sending a single crafted record with the content-type header set to application/cloudevents+json but omitting required CloudEvent attributes (id, source, type), an ArgumentException is triggered in KafkaMessageConsumer.SingleMessageHandlingAsync. This exception is treated as fatal, causing the host to stop and re-process the same poison record on every restart, resulting in a permanent crash-loop.
Potential Impact
An unauthenticated remote attacker can cause a denial-of-service by crashing the Motor.NET service permanently. The service enters a crash-loop on restart due to re-processing the same malformed record, leading to service unavailability until manual intervention or patching.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, avoid processing records with the content-type application/cloudevents+json that omit required CloudEvent attributes (id, source, type).
