Denial-of-Service via Magic Link Authentication in WSO2 Identity Server Allows Service Unavailability_CVE-2025-10470

{
    "lastseen": "",
    "description": "The Magic Link authentication flow accepts multiple invalid authentication requests without adequate rate limiting or resource control, leading to uncontrolled memory usage growth.\n\nThis vulnerability can result in a denial-of-service condition, causing service unavailability for deployments that utilize the Magic Link authenticator. The impact is limited to these specific deployments and requires repeated invalid authentication attempts to trigger.",
