Multilingual Prompt Injection Detection With Machine Translated Adversarial Datasets

via “multilingual prompt injection detection with machine-translated adversarial datasets”

Meta's prompt injection and jailbreak detection classifier.

Unique: Leverages CyberSecEval's multilingual dataset (mitre_prompts_multilingual_machine_translated.json) to provide single-model multilingual detection rather than language-specific classifiers, reducing deployment complexity while acknowledging translation-based limitations

vs others: Single unified model for multiple languages versus maintaining separate classifiers per language; trades off native-speaker accuracy for operational simplicity and consistency
