Lockdown Mode is available to logged-in users across Free, Go, Plus, and Pro, and self-serve ChatGPT Business plans.<\/p>\n<p>&#8220;Lockdown Mode is an optional advanced security setting that limits many tools and capabilities in OpenAI products that can connect to the web or external services,&#8221; OpenAI said.<\/p>\n<p>&#8220;It is designed to reduce the risk of data exfiltration from prompt injection attacks by limiting outbound network requests, at the expense of disabling or limiting some useful features.&#8221;<\/p>\n<p>The safeguards are aimed at hardening the attack surface against prompt injections, which continues to be a &#8220;frontier&#8221; problem impacting all large language models (LLMs).<\/p>\n<p>Specifically, they build upon sandboxing and existing controls to combat URL-based data exfiltration mechanisms to limit outbound network requests that could potentially transmit sensitive data to attacker-controlled infrastructure.<\/p>\n<p>The idea is not to stop prompt injections from occurring. Nor does it change the way memory or file uploads work, or the ability to share a conversation. Rather, the goal is to eliminate potential pathways through which the data could be exfiltrated. To that end, Lockdown Mode disables the following features &#8211;<\/p>\n<ul>\n<li>Live web browsing, which is limited to accessing only cached content<\/li>\n<li>Image support, for displaying images in regular responses or retrieving images from the web<\/li>\n<li>Deep research<\/li>\n<li>Agent mode<\/li>\n<li>Canvas networking, which prevents users from approving Canvas-generated code to access the network<\/li>\n<li>File downloads, which block downloading files for data analysis<\/li>\n<\/ul>\n<p>Pointing out the feature is not &#8220;intended for&#8230;<\/p>\n<p><a href=\"https:\/\/thehackernews.com\/2026\/06\/new-chatgpt-lockdown-mode-limits-tools.html\">Source<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>New ChatGPT Lockdown Mode Limits Tools That Could Enable Data Exfiltration https:\/\/thehackernews.com\/2026\/06\/new-chatgpt-lockdown-mode-limits-tools.html Publish Date: 2026-06-06&#8230;<\/p>\n","protected":false},"author":1,"featured_media":265849,"comment_status":"closed","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"fifu_image_url":"https:\/\/blogger.googleusercontent.com\/img\/b\/R29vZ2xl\/AVvXsEhBOQJLNqTRWigWAgPKNCKXr8hOgMZD4ZNb3lNzGbrvSj87BzK_VzrbaqMPVOo1wmCsILPHO2s5cdfu1I2nUOhNibPpzsOHko3qWQwCVXXVdi8yaqYjMJGBD6Fzz-eBmgJ1-Vy0E02L_X1xsT3neUlTTsn9s8e2ODQVYXNErvOz9VrHEIdJNfGhsASUV0ag\/s1600\/chatgpt-lockdown.jpg","fifu_image_alt":"","footnotes":""},"categories":[15],"tags":[20,24],"class_list":["post-265848","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-cybersecurity","tag-artificial-intelligence","tag-cybersecurity"],"_links":{"self":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/265848"}],"collection":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/comments?post=265848"}],"version-history":[{"count":1,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/265848\/revisions"}],"predecessor-version":[{"id":265851,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/265848\/revisions\/265851"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/media\/265849"}],"wp:attachment":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/media?parent=265848"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/categories?post=265848"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/tags?post=265848"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
