On June 4, Asana recognized a bug in its Mannequin Context Protocol (MCP) server and took the server offline to research. Whereas the incident was not the results of an exterior assault, the bug might have uncovered knowledge belonging to Asana MCP customers to customers in different accounts.
What Occurred
In accordance with Asana’s disclosure, the bug “could have potentially exposed certain information from your Asana domain to other Asana MCP users.” Particularly, customers leveraging the MCP interface—sometimes for LLM-powered chat interfaces—could have been capable of entry knowledge from different organizations, however solely throughout the “projects, teams, tasks, and other Asana objects” of the MCP person’s permissions.
There isn’t any indication that attackers exploited the bug or that different customers truly considered the knowledge accessible by way of the MCP bug. Asana emphasizes: “This was not a result of a hack or malicious activity on our systems.”
Timeline and Response
Asana responded shortly upon discovery of the bug:
Could 1. Asana releases the MCP server. The bug seems to have been a part of this preliminary launch. June 4: The MCP bug was recognized, Asana took the server offline, and resolved the code concern. They write: “Our incident responders and engineering teams acted immediately. As soon as the vulnerability was discovered on June 4, we took the MCP server down to investigate, contain the issue and prevent any further potential exposure. The bug in our code was then promptly resolved.”June 16: Asana notified doubtlessly affected clients–anybody with a person who used the MCP server. Ongoing: Asana is working to deliver the MCP server again on-line. Moreover, they’ve despatched out a kind for affected corporations to contact them to get an inventory of all Asana customers with the MCP servers who could have doubtlessly had their knowledge learn by others.
Prospects have been given the power to request logs and metadata related to their MCP customers to find out whether or not cross-account knowledge publicity could have occurred. Asana advises organizations to “review any information you may have accessed through the MCP server in recent weeks and immediately delete any data that doe
Asana’s Next Steps
Asana reports that the MCP server will be reinstated “in the coming days,” however reconnection will probably be handbook. “We want to ensure your team is aware of the issue we experienced, and that you have full control over when your Asana instance reconnects to the MCP server.”
The corporate additionally confirmed {that a} formal autopsy report is underway and will probably be out there upon request when accomplished.
Takeaways for Organizations Utilizing LLM Integrations
This incident highlights key classes for any group integrating LLMs into delicate workflows:
Restrict scope aggressively: Be sure that context servers like MCP implement strict tenant isolation and least-privilege entry.Log every part: Keep granular logs of all requests, particularly LLM-generated queries, to assist forensic investigations.Guide oversight throughout reintroduction: Automated reconnections or retraining pipelines ought to be paused when incidents come up.Deal with inner bugs severely: As proven right here, even inner software program flaws can have real-world publicity penalties.
Asana’s transparency in dealing with the incident and proactive communication are commendable, however the episode underscores the dangers inherent in LLM system design, particularly when built-in with enterprise knowledge platforms.
