Multiple account creation via non-atomic invite consumption
Published Apr 6, 2026 · Updated Apr 6, 2026
Race condition in Homarr before 1.57.0 allows remote authenticated users to create multiple accounts with one invite token. The /api/trpc/user.register flow checks the token, creates an account, and deletes the token in separate database operations without a transaction. Concurrent requests holding a valid invite token can pass the check before deletion, bypassing its single-use limit and adding unauthorized accounts.
