CVE-2026-112330 Details
Description
Motor.NET before 0.19.0 contains a denial of service vulnerability that allows a remote attacker who can publish to a consumed queue to crash the service permanently by sending a message with crafted cloudEvents headers. Attackers can supply an invalid cloudEvents:motorversion, a single double-quote header value, or an unparsable typed attribute such as cloudEvents:time to trigger an unhandled exception in ExtractCloudEvent that is treated as fatal, causing the application to stop and the unacknowledged message to be redelivered on restart, resulting in a permanent crash-loop.
A denial-of-service vulnerability has been identified in Motor.NET versions prior to 0.19.0. This issue allows remote attackers who can publish to a consumed RabbitMQ queue to cause a permanent crash of the service. The vulnerability is triggered by sending messages with specially crafted CloudEvents headers, such as an invalid 'cloudEvents:motorversion', a header value containing a single double-quote, or an unparsable typed attribute like 'cloudEvents:time'. These invalid inputs cause an unhandled exception in the 'ExtractCloudEvent' method, which is treated as fatal, leading the application to stop. When the service is restarted, the unacknowledged message is redelivered, causing a continuous crash-loop.
Users can upgrade to Motor.NET version 0.19.0 or later, where this vulnerability has been fixed.
