Malicious Browser Extensions Could Use Claude Dispatch to Run Code on Users’ Computers
What happened
Researchers at Forever Security demonstrated how malicious browser extensions could exploit Claude Dispatch, a feature in claude.ai, to execute code on users’ computers through Claude Desktop. The Dispatch feature allows users to send tasks from their phones to the desktop app. The researchers confirmed that a vulnerability enabling this exploitation still exists as of their latest tests.
The risk
This vulnerability creates a pathway for browser extensions to run arbitrary scripts remotely on a user’s machine via Claude Desktop. Since browser extensions often have elevated permissions and access to web content, they can leverage Dispatch to bypass normal security restrictions. This turns the convenience of remote task dispatch into a potential attack vector for malware or unauthorized access.
Why it matters
Businesses and individuals using Claude Desktop should reassess the risk posed by extensions they have installed on browsers that interact with claude.ai sessions. The issue pressures developers and customers to demand stronger safeguards around inter-device communication features in AI tools. It also raises the stakes for endpoint security strategies since even trusted AI-powered workflows can become entry points for code execution attacks.
Who should pay attention
IT security teams, AI platform operators, and power users leveraging Claude Desktop alongside connected devices must prioritize monitoring for suspicious app activity. Browser extension reviewers and developers should scrutinize permission scopes that touch AI service integrations. Investors and founders in AI applications with cross-device features should factor this risk into product design and customer assurance.
What to watch next
Watch for official patches from the Claude.ai team addressing the Dispatch vulnerability. Security vendors may update endpoint protection to detect exploitation attempts involving AI dispatch features. Regulatory scrutiny could increase on AI platforms that allow remote code triggering via consumer-grade apps and extensions. Users should track updates to recommended security practices around browser extensions and AI desktop apps.
