Details

A flaw has been found in UsamaK98 python-notebook-mcp up to a05a232815809a7e425b5fa7be26e0d4369894c2. Impacted is the function create_notebook/read_notebook/edit_cell/add_cell of the file server.py. This manipulation causes path traversal. It is possible to initiate the attack remotely. The exploit has been published and may be used. This product is using a rolling release to provide continious delivery. Therefore, no version details for affected nor updated releases are available. The project was informed of the problem early through an issue report but has not responded yet.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
