Security firm ClawSecure has identified critical vulnerabilities in 14 artificial intelligence models across five testing labs. The findings suggest that attackers can bypass safety protocols to manipulate AI agents integrated with platforms like Dropbox, Notion, and Linear.
Why it matters
The discovery highlights a significant security gap in AI agent ecosystems where unauthorized instructions embedded in common documents or support tickets can force agents to execute harmful actions. ClawSecure has consequently advised businesses to suspend all active AI agents until proper security assessments are in place.
Testing evaluated 14 distinct artificial intelligence models across five separate labs to identify potential exploit vectors. The results demonstrate that agents with access to infrastructure or financial accounts remain susceptible to unauthorized manipulation.
The players
ClawSecure
A cybersecurity firm that monitors AI model vulnerabilities and coordinates exploit reporting to model providers.
J.D. Salbego
A representative of ClawSecure who has presented findings on AI agent security to congressional offices and the Federal Trade Commission.
The details
Researchers utilized indirect prompt injection, a method where attackers hide malicious instructions within emails, shared documents, or support tickets. When an AI agent accesses these files or tickets, it misinterprets the hidden text as a legitimate command, potentially executing unauthorized actions within connected services. This vulnerability stems from the agent's ability to read and act on external content without sufficient oversight or credential verification.

The Tech Race
This vulnerability report signals an intensifying push toward rigorous, standardized safety ratings for AI agents. ClawSecure aims to bridge the gap between current ad-hoc security practices and a formal institutional testing framework capable of auditing model integrations.
Businesses currently using AI agents for workflow automation in Dropbox, Notion, or Linear should consider pausing these integrations immediately. Users remain at risk until providers implement stronger sanitization for incoming data and documents that agents are permitted to access.
The takeaway
The security of AI agents depends on solving the fundamental issue of indirect prompt injection across widely used enterprise tools. Readers should watch for updates from the Federal Trade Commission as policymakers continue to engage with security firms like ClawSecure on potential safety standards.
