Global Security Blind Spots: Translation as a Safety Bypass in Low-Resource Languages

Safety guardrails in ten major LLMs collapse when harmful prompts are simply translated into low-resource languages — a critical gap for European enterprises deploying multilingual AI under EU AI Act obligations.

arXiv:2610.27304v1 Announce Type: cross Abstract: Large language models are deployed globally, yet safety alignment and evaluation remain concentrated in English: harmful requests refused in English can elicit unsafe completions when translated into low-resource languages. We evaluate ten widely deployed LLMs across 79 languages (English plus 78 low-resource) under a translation-bypass threat model, using a metric conditioned on English safety, which separates translation bypass from unsafety a

Editorial Analysis

Why it matters

European enterprises serve diverse language communities; LLM safety alignment that works only in English creates regulatory and reputational exposure under the EU AI Act.

What to do

Mandate multilingual adversarial testing — including low-resource EU languages — for any customer-facing LLM deployment.

Board brief

LLM safety filters that work in English fail in smaller languages, creating legal and reputational risk for multilingual European deployments.
