A user who entered a question in a foreign language followed by an English meta-instruction caused the service to answer the question instead of translating it. Security researchers reported that the technique could produce dangerous content, including instructions for making drugs and malware. A Tumblr user first discovered the behaviour, and it was publicised by a jailbreaker and reported in the press. As of February 10, 2026, the vulnerability remained active in production, and Google had not issued a public statement or a timeline for a fix.","tags":[],"date_detected":null,"near_miss":null,"root_cause":null,"root_cause_detail":null,"failure_class_detail":null,"responsible_party":null,"adversarial_actor":null,"input_provenance":null,"time_to_contain":null,"operations_paused":null,"remediation":null,"precursor_events":null,"primary_risk":"RK01","secondary_risks":["RK12"]},"impact":{"direct_loss_usd":null,"remediation_hours":null,"records_exposed":null,"third_parties_affected_count":null,"severity":"major","harm_class":[],"affected_description":null,"protected_class_involved":null,"data_categories_exposed":[],"loss_range_usd":null,"reversibility":null,"downstream_exposure_count":null},"evidence":{"sources":[{"url":"https://winbuzzer.com/2026/02/10/google-translate-gemini-prompt-injection-vulnerability-xcxwbn/","publisher":"WinBuzzer","date":"2026-02-10","type":"press","title":"Google Translate’s Gemini Mode is Vulnerable to Prompt Injection - WinBuzzer","archived_url":null,"attachment":"first_report"}],"per_field_confidence":{"system.deployment_context":"C","system.lifecycle_stage":"C","event.trigger":"C","event.detection_method":"C","event.incident_class":"D","impact.severity":"D","event.primary_risk":"D","event.secondary_risks":"D","event.summary":"C","system.autonomy_level":"D","context.country":"D","system.developer":"D","event.date_disclosed":"D","context.denominator_available":"D"},"field_citations":{"system.deployment_context":[{"source_index":0,"quote":"As of February 10, the vulnerability remains active in Google Translate’s production system, affecting users worldwide who rely on the service for daily translation needs."}],"system.lifecycle_stage":[{"source_index":0,"quote":"As of February 10, the vulnerability remains active in Google Translate’s production system, affecting users worldwide who rely on the service for daily translation needs."}],"event.trigger":[{"source_index":0,"quote":"Google Translate can be tricked into generating dangerous content instead of translations through simple prompt injection attacks discovered this week that exploit its Gemini AI foundation."}],"event.detection_method":[{"source_index":0,"quote":"A Tumblr user discovered that entering a question in a foreign language like Chinese, then adding an English meta-instruction below it, causes the service to abandon its core function."}],"event.incident_class":[{"source_index":0,"quote":"Google Translate can be tricked into generating dangerous content instead of translations through simple prompt injection attacks discovered this week that exploit its Gemini AI foundation."}],"impact.severity":[{"source_index":0,"quote":"As of February 10, the vulnerability remains active in Google Translate’s production system, affecting users worldwide who rely on the service for daily translation needs."}],"event.summary":[{"source_index":0,"quote":"Google Translate can be tricked into generating dangerous content instead of translations through simple prompt injection attacks discovered this week that exploit its Gemini AI foundation."},{"source_index":0,"quote":"Instead of translating the text, Google Translate answers the question."},{"source_index":0,"quote":"A Tumblr user discovered that entering a question in a foreign language like Chinese, then adding an English meta-instruction below it, causes the service to abandon its core function."},{"source_index":0,"quote":"Despite this systemic risk, Google has not issued a public statement about the vulnerability or provided a timeline for addressing the security flaw."}]},"notes_on_gaps":"Single press source (WinBuzzer), no statement from Google and no primary report. Not stated: the exact Gemini model (the system's self-claim of Gemini 1.5 Pro was judged unreliable by the source and is not recorded), the date the flaw occurred or was detected, the disclosure date, the number of affected users or any count of affected parties, any financial loss, and any remediation. Judgements: the source's 2026-02-10 publication date is not used as a disclosure date; no autonomous agent was described, so agent_involved and failure_class are left out; detection is labelled public_researcher because the discoverer was a Tumblr user; severity is major because the scope is stated as users worldwide (unbounded); root_cause is guardrail based on the source's account of missing instruction boundaries; C1 and D1 are marked failed and I5 missing from the source's statements; no controls are asserted as held because the sources state none. Pliny the Liberator's claims are reported as the source reports them, not verified. The article's architectural claims are opinion-like and are attributed to the source, not stated as fact.
