Vulnerability from github – Published: 2026-04-03 18:31 – Updated: 2026-04-03 18:31

Details

A vulnerability has been found in NASA cFS up to 7.0.0. The impacted element is the function pickle.load of the component Pickle Module. Such manipulation leads to deserialization. The attack needs to be performed locally. The attack requires a high level of complexity. The exploitability is regarded as difficult. The exploit has been disclosed to the public and may be used. The project was informed of the problem early through an issue report but has not responded yet.

Detection rules are retrieved from Rulezet.

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.
