CVE-2026-112332 Details
Description
Motor.NET before 0.19.0 contains an uncaught exception vulnerability in JsonNetDeserializer.Deserialize that allows a remote attacker who can publish to a consumed queue or topic to crash the service permanently by sending structurally valid JSON that does not match the handler's expected type. Attackers can exploit the fact that JsonSerializationException is not caught alongside JsonReaderException and InvalidCastException, causing TypedConsumerService.SingleMessageConsumeAsync to treat the error as CriticalFailure and call StopApplication, which combined with the unacknowledged message being redelivered on restart results in a permanent crash-loop.
A denial-of-service vulnerability has been identified in Motor.NET versions prior to 0.19.0. The issue arises from an uncaught exception in the JsonNetDeserializer.Deserialize method, allowing remote attackers to crash the service permanently. This is achieved by sending structurally valid JSON that does not align with the expected type. The vulnerability exploits the fact that JsonSerializationException is not handled alongside JsonReaderException and InvalidCastException. As a result, when TypedConsumerService.SingleMessageConsumeAsync encounters this error, it is treated as a CriticalFailure, leading to a call to StopApplication. This, combined with the unacknowledged message being redelivered upon restart, creates a permanent crash-loop.
Users can upgrade to Motor.NET version 0.19.0 or later, where this vulnerability has been fixed.
