Discord server protection service Double Counter disclosed a data breach on October 4, 2026, attributed to a vulnerability in the Metabase analytics tool. Attackers accessed a subset of the service’s data, and a subsequently published corpus contained approximately 275,000 unique email addresses, along with Discord usernames. Have I Been Pwned added the breach to its records on October 7.
The exposed data also included a small number of paying subscribers’ records containing names, countries, and postcodes, associated with purchases processed through Stripe; the reported incident does not establish a breach of Stripe itself. The combination of email addresses, Discord identities, and subscriber details creates opportunities for targeted phishing and impersonation. Affected users should be alert to messages posing as Double Counter or payment support, while organizations operating Metabase should review security updates and restrict access to analytics systems.
