Unauthenticated API interruption via unbounded GraphQL operations
Published Apr 8, 2026 · Updated Apr 8, 2026
Resource exhaustion in Saleor allows remote attackers to interrupt the GraphQL API through a crafted unauthenticated request. The GraphQL request pipeline accepted unlimited aliases and mutations because its cost validation did not count either construct, allowing one call to trigger excessive repeated work. No authentication or user interaction is required, and the documented consequence is availability loss rather than data disclosure or modification.
