CVE-2026-125114
Novu: SSRF via conditions filter webhook bypasses validateUrlSsrf() protection
Novu provides an API for sending notifications through multiple channels. Prior to 3.15.0, the conditions filter webhook in libs/application-generic/src/usecases/conditions-filter/conditions-filter.usecase.ts passes the user-configured child.webhookUrl directly to axios.post without calling validateUrlSsrf. Evaluating a workflow condition can therefore make the worker send a POST request to a private or link-local service and return the response data for condition evaluation. The response is stored in execution details and exposed through GET /execution-details, which can disclose credentials from POST-capable metadata services or data from internal services, although metadata endpoints that require GET are not reachable through this path. This issue is fixed in version 3.15.0.
