Detailsinfo

A vulnerability classified as problematic was found in DaguCloud Dagu up to 2.10.x. This vulnerability affects the function dagu_read of the component MCP. The manipulation with an unknown input leads to a path traversal vulnerability. The CWE definition for the vulnerability is CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. As an impact it is known to affect confidentiality. CVE summarizes:

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.

The advisory is shared for download at github.com. This vulnerability was named CVE-2026-102943 since 09/29/2026. The exploitation appears to be easy. The attack can be initiated remotely. There are known technical details, but no exploit is available. The MITRE ATT&CK project declares the attack technique as T1006.

Upgrading to version 2.11.0 eliminates this vulnerability.
