CVE detail

CVE-2026-73247

Kestra is an open-source, event-driven orchestration platform. Prior to 2.0.0, Kestra's core/src/main/java/io/kestra/core/runners/pebble/functions/HttpFunction.java passes the user-controlled http() uri argument to URI.create() and the server-side HTTP client without restricting private, loopback, or link-local destinations, allowing an unauthenticated attacker to import and execute a flow that accesses internal services or cloud metadata.
