A security issue was discovered in the LRA Coordinator component of Narayana. When Cancel is called in LRA, an execution time of approximately 2 seconds occurs. If Join is called with the same LRA ID within that timeframe, the application may crash or hang indefinitely, leading to a denial of service.
