Summary

CordysCRM is an open source AI-powered customer relationship management system that supports private deployment. In version 1.7.3, ApprovalResourceService.sendWebHook reads WebHookConfig.webHookUrl from stored approval-node configuration and passes it through ApprovalFlowService.updateApprovalPostField to HttpClientUtils without the SSRF validation used by the optional testConnect path. A user with PROCESS_SETTING_ADD can configure an internal URL through POST /approval-flow/add and cause the server to request it when POST /approval-action/approve executes the approval action, enabling cloud metadata access, internal network reconnaissance, and interaction with reachable internal services. This issue is fixed in version 1.7.4.
