CVE-2026-67545
highHeym builds and runs agentic systems and business-process automations on self-hosted infrastructure.
Heym builds and runs agentic systems and business-process automations on self-hosted infrastructure. Prior to version 0.0.73, the HTTP workflow node in Heym makes outbound HTTP requests to user-supplied URLs without validation of the target host or IP address. If a workflow author has already configured an HTTP node that targets internal addresses such as cloud metadata endpoints or private network hosts, and exposed the workflow with anonymous execution, an unauthenticated attacker can trigger the preconfigured SSRF sink. The same project has comprehensive SSRF protection in its MCP integration, which is absent from the HTTP node. This issue has been patched in version 0.0.73.
