An intruder reached a legacy system at OpenCode on the night of October 16 and may have exposed the third-party AI provider keys that users had saved in OpenCode Console, the company said.

Console is OpenCode's optional hosted service: a workspace saves its own OpenAI, Anthropic, or Google key there, and Console uses that key to call the provider so team members can use the models without ever seeing the key.

The affected group is 1.4% of Console users, all of whom have an outside provider linked, and OpenCode has told them via email to revoke those keys with each provider and replace them.

The email went out on the morning of October 17 under the subject line "Action Required: Potential provider key breach." Anyone who did not get one was not affected, OpenCode said in a post on X later that day.

The keys at risk are the ones pasted into Console. The OpenCode command-line and desktop apps keep provider keys added on the machine in a SQLite database there. The breach involves "the OpenCode Console, not OpenCode itself," co-founder Dax Raad wrote in a reply on X, and those keys "never come to us."

A provider key is a bearer credential: whoever holds a copy can run billable requests against the owner's account until the provider revokes it. Deleting the key from Console does not revoke it, and a Console budget cannot cap that use either, because Console only sees requests that pass through its own gateway.
