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.
Update WSO2/WSO2 API Control Plane to 4.5.0.55; WSO2/WSO2 API Manager to 3.2.0.470; WSO2/WSO2 Traffic Manager to 4.5.0.53; WSO2/WSO2 Universal Gateway to 4.5.0.54 if you use the affected versions. Test the change in a non-production environment first.

hol-guard supply-chain scanDenial of Service via Malicious JSON Payloads in Throttling Events in Multiple WSO2 Products Causing Persistent Service Disruption affects WSO2/WSO2 API Control Plane (generic), WSO2/WSO2 API Manager (generic), WSO2/WSO2 Traffic Manager (generic), WSO2/WSO2 Universal Gateway (generic). Severity is high. 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.
AI coding agents often install or upgrade packages automatically in generic. A high vulnerability in a dependency can be pulled into a project through a normal install or update without a human reviewing the change, expanding the blast radius from a single package to every agent workspace that depends on it.
