Description

Dagu is a workflow engine with a built-in Web user interface. Prior to version 2.11.0, its MCP  dagu_read  operation with target  dag_spec  invokes the DAG specification API directly, bypassing the HTTP middleware introduced for CVE-2026-33344. The underlying resolver does not restrict resolved paths to configured DAG directories. An authenticated attacker with a viewer-role API key can supply an absolute or traversing path to read  .yaml  or  .yml  files outside those directories that are accessible to the Dagu process. The affected operation does not provide write or execution capability. This issue is fixed in version 2.11.0.
