CWE-707Improper Neutralization

Description

The throttling event handling mechanism in multiple WSO2 products accepts user-supplied JSON payloads without sufficient validation of their structure and content. This allows an unauthenticated remote attacker to inject malicious JSON data that can lead to a persistent denial of service condition. Successful exploitation of this vulnerability can disrupt the API Gateway, preventing legitimate API traffic from being processed and impacting complete service availability. The denial of service is persistent, requiring manual intervention to restore normal operations.
