Summary

blamer vulnerable to Arbitrary Argument Injection via the blameByFile() API

Details

Versions of the blamer package before 1.0.4 are vulnerable to Arbitrary Argument Injection via the blameByFile() API. The library does not sanitize for user input or validate the given file path conforms to a specific schema, nor does it properly pass command-line flags to the git binary using the double-dash POSIX characters (--) to communicate the end of options.

Severity

6.5 (Medium)

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.
