The feature disables several ChatGPT capabilities including live web browsing, image retrieval, deep research, and agent mode to reduce the risk of sensitive data being exposed, though OpenAI acknowledges that prompt injections could still occur through cached content or uploaded files.","solution":"OpenAI's explicit mitigation is Lockdown Mode, which \"will disable live web browsing (so you can only access cached content), the retrieval and display of images from the web (you can still generate images), deep research, and agent mode.\" The feature is being rolled out to ChatGPT Business accounts and eligible personal accounts. OpenAI states the goal is \"to reduce the likelihood that sensitive data gets shared in the process.\"","labels":["security","safety"],"sourceUrl":"https://techcrunch.com/2026/06/06/openai-unveils-lockdown-mode-to-protect-sensitive-data-from-prompt-injection-attacks/","publishedAt":"2026-06-06T20:32:24.000Z","cveId":null,"cweIds":null,"cvssScore":null,"cvssSeverity":null,"severity":"info","attackType":["prompt_injection"],"issueType":"news","affectedPackages":null,"affectedVendors":["OpenAI"],"affectedVendorsRaw":["OpenAI","ChatGPT"],"classifierModel":"claude-haiku-4-5-20251001","classifierPromptVersion":"v3","cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":null,"epssScore":null,"patchAvailable":null,"disclosureDate":"2026-06-06T20:32:24.000Z","capecIds":null,"crossRefCount":0,"attackSophistication":"moderate","impactType":["confidentiality","integrity"],"aiComponentTargeted":"api","llmSpecific":true,"classifierConfidence":0.92,"researchCategory":null,"atlasIds":null}}
