Detailsinfo

A vulnerability was found in REYu6 MetaGPT 0.8.1. It has been rated as problematic. This issue affects the function set_file_name/load_meta_data of the file metagpt/ext/spo/utils/load.py of the component SPO extension. The manipulation of the argument FILE_NAME with an unknown input leads to a path traversal vulnerability. Using CWE to declare the problem leads to 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. Impacted is confidentiality. The summary by CVE is:

A path traversal vulnerability in the SPO extension of MetaGPT 0.8.1 allows an attacker to read arbitrary files via the FILE_NAME value used by set_file_name() and load_meta_data() in metagpt/ext/spo/utils/load.py. The vulnerable code joins the attacker-controlled FILE_NAME value with the settings directory and opens the resulting path without validating that the resolved path remains within the intended directory.

It is possible to read the advisory at github.com. The identification of this vulnerability is CVE-2026-79407 since 08/25/2026. The exploitation is known to be easy.
