CVE-2026-33756 PUBLISHED

Saleor Affected by Denial of Service via Unbounded GraphQL Query Batching

Assigner: GitHub_M
Reserved: 23.03.2026 Published: 08.04.2026 Updated: 08.04.2026

Saleor is an e-commerce platform. From 2.0.0 to before 3.23.0a3, 3.22.47, 3.21.54, and 3.20.118, Saleor supports query batching by submitting multiple GraphQL operations in a single HTTP request as a JSON array but wasn't enforcing any upper limit on the number of operations. This allowed an unauthenticated attacker to send a single HTTP request many operations (bypassing the per query complexity limit) to exhaust resources. This vulnerability is fixed in 3.23.0a3, 3.22.47, 3.21.54, and 3.20.118.
