While\u00a0much of the discussion on AI security centers around protecting\u00a0\u2018shadow\u2019 AI and GenAI consumption, there’s a wide-open\u00a0window nobody’s guarding: AI browser extensions.\u00a0<\/p>\n

A\u00a0new report from LayerX\u00a0exposes<\/a> just how deep this blind spot goes, and why AI extensions may be the most dangerous AI threat surface in your network\u00a0that isn’t\u00a0on anyone’s\u00a0radar.<\/p>\n

AI\u00a0browser extensions don’t trigger your DLP\u00a0and don’t show up in your SaaS logs. They\u00a0live inside the browser itself, with direct access to everything your employees see, type, and stay logged\u00a0into. AI\u00a0extensions are 60% more likely to have a vulnerability than extensions on\u00a0average, are 3 times more likely to have access to cookies, 2.5\u00a0times more\u00a0likely to be\u00a0able to execute remote scripts in the browser, and 6 times more likely to have increased their permissions in the past\u00a0year. These\u00a0extensions install in seconds and can remain in your environment indefinitely.\u00a0<\/p>\n

The Browser Extension Threat Surface Is Everybody, Yet Nobody Is\u00a0Watching<\/h2>\n

The\u00a0first misconception is that extensions are a niche risk. Something limited to a subset of users or edge cases. That\u00a0assumption is completely\u00a0wrong.<\/p>\n

According to the report, 99% of enterprise\u00a0users run at least one browser extension, and more than a quarter\u00a0have over 10 installed. This\u00a0is not a long tail problem; it is universal.<\/p>\n

Yet\u00a0most organizations cannot answer basic questions. Which\u00a0extensions are in use? Who installed them? What permissions do they have? What data can they\u00a0access?<\/p>\n

Security teams have spent years building visibility into networks, endpoints, and identities. Ironically, browser extensions remain a major blind\u00a0spot.\u00a0<\/p>\n

AI Extensions Are The AI Consumption Channel That Nobody Talks\u00a0About\u00a0<\/h2>\n

While\u00a0much of the current conversation around AI security focuses on SaaS platforms and APIs, this report highlights a\u00a0different and\u00a0largely ignored channel: AI browser extensions.<\/p>\n

These\u00a0tools are spreading quickly.\u00a0About 1-in-6 enterprise users already use at least one AI extension, and that number is only\u00a0growing.<\/p>\n

\"\"<\/a><\/div>\n

Organizations may block or monitor direct access to AI applications. But\u00a0extensions operate differently. They\u00a0sit inside the browser. They\u00a0can access page content, user inputs, and session data without triggering traditional\u00a0controls.<\/p>\n

<\/p>\n

In effect, they create an ungoverned layer of AI usage, one that bypasses visibility and policy enforcement.<\/p>\n

AI Extensions Are Not Just Popular. They\u00a0Are\u00a0Riskier<\/h2>\n

It would be easy to assume that AI extensions carry\u00a0a similar risk to other extensions. The data shows otherwise.<\/p>\n

AI extensions are significantly more dangerous. They are 60% more likely to have a CVE than average, 3x more likely to have access to cookies, 2.5x\u00a0more likely to have scripting permissions, and 2x more\u00a0likely to be\u00a0able to manipulate browser\u00a0tabs.\u00a0<\/p>\n

\"\"<\/a><\/div>\n

Each of these permissions carries real implications. Cookie\u00a0access can expose session tokens. Scripting enables data extraction and manipulation. Tab\u00a0control can facilitate phishing or silent redirection.<\/p>\n

This combination\u00a0of fast\u00a0adoption, elevated access, and weak governance makes AI extensions an urgent emerging threat\u00a0vector.<\/p>\n

Extensions Are Not Static. They\u00a0Change Over\u00a0Time<\/h2>\n

Security teams often treat extensions as static. Something\u00a0that can be\u00a0approved once and forgotten.\u00a0But that\u2019s not how it\u00a0works.<\/p>\n

Extensions evolve. They\u00a0receive updates. They\u00a0change ownership. They\u00a0expand permissions.<\/p>\n

The report shows that AI extensions are nearly six times more likely to change their permissions over time, and that more than 60% of users have at least one AI extension that has changed its permissions in the past\u00a0year.<\/p>\n

This creates a moving target that traditional allowlists cannot keep up with. An\u00a0extension that was safe yesterday may not be safe\u00a0today.<\/p>\n

\"\"<\/a><\/div>\n

The Trust Gap in Browser Extensions Is Wider Than\u00a0Expected<\/h2>\n

Security teams rely on a range of trust signals to evaluate extensions, including publisher transparency, install counts, update frequency, and the presence of a privacy policy. While\u00a0these do not directly indicate malicious behavior, they are key to assessing overall\u00a0risk.\u00a0<\/p>\n

A significant portion of extensions have very low user bases. More\u00a0than 10% of all extensions have fewer than 1,000 users, a quarter have fewer than 5,000 users, and a third have fewer than 10,000 installations. This is particularly a\u00a0challenge with AI extensions, where\u00a033% of AI extensions have fewer than 5,000\u00a0users, and nearly\u00a050% of AI extensions\u00a0have less than 10,000\u00a0users.A large user base is essential for establishing ongoing trust, but once again, AI extensions are\u00a0showing substantially higher\u00a0risk.<\/p>\n

Moreover, around 40% of extensions haven\u2019t received an update in over a year, suggesting that they are no longer actively maintained. Extensions that are not regularly updated may contain unresolved vulnerabilities or outdated code that attackers\u00a0exploit.<\/p>\n

As a result, most extensions used in enterprise environments show weak or missing signals across these\u00a0areas. This raises serious questions about data handling and compliance. It\u00a0also highlights how little scrutiny extensions receive compared to other software components.<\/p>\n

Turning Insight into Action: The Path Forward for\u00a0CISOs<\/h2>\n

The report outlines a clear direction for security\u00a0teams:<\/p>\n

    \n
  1. Continuously Audit The Organization’s Extension Threat\u00a0Surface:<\/strong> With 99% of enterprise users running at least one extension, a full inventory is a mandatory first step toward risk reduction. CISOs\u00a0should do an organization-wide extension audit covering all\u00a0browsers, managed and unmanaged\u00a0endpoints, across all\u00a0users.<\/li>\n
  2. Apply\u00a0Targeted Security Controls to AI Extensions:\u00a0<\/strong>AI extensions represent an outsized risk due to their elevated permissions that can expose SaaS sessions, identities, and sensitive in-browser\u00a0data. Organizations should apply stricter governance policies to control how these extensions interact with enterprise environments.<\/li>\n
  3. Analyze Extension Behavior, Not Just Static Parameters:<\/strong> Static approvals are not sufficient. Risk\u00a0needs to be continuously assessed based on permissions, behavior, and changes over\u00a0time.\u00a0<\/li>\n
  4. Enforce Trust and Transparency Requirements:<\/strong> Extensions that have very low install counts, lack privacy policies, or show poor maintenance history\u00a0should be\u00a0treated as higher risk. Establishing minimum trust criteria helps reduce exposure to unverified or abandoned extensions.<\/li>\n<\/ol>\n

    A New Lens On An Old\u00a0Problem<\/h2>\n

    For years, browser extensions\u00a0have been\u00a0treated as a convenience feature. Something to enable productivity and customization. However, they are no longer a peripheral risk. They\u00a0are a core part of the enterprise attack surface. Widely\u00a0used, highly privileged, and largely unmonitored, they create direct exposure to sensitive data and user\u00a0sessions.\u00a0<\/p>\n

    Download the full Extension Security\u00a0report<\/a> from LayerX to understand the full scope of these findings, identify where your exposure truly lies, and get a clear path to controlling this growing attack surface without disrupting productivity.<\/p>\n
