CVE-2026-9673

A flaw was found in json-2-csv. An attacker can bypass the `preventCsvInjection` option to inject malicious formulas into CSV (Comma Separated Values) files. When these manipulated CSV files are opened in spreadsheet applications, the injected formulas can execute, potentially leading to arbitrary code execution or information disclosure.

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.
