CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:HSummary
CVE-2026-33756 is a high-severity Allocation of Resources Without Limits or Throttling (CWE-770) vulnerability in Saleor Saleor. Its CVSS base score is 7.5 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Network Denial of Service (T1498); ranked at the 36th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to AC-10 (Concurrent Session Control) and SC-6 (Resource Availability) — see the control section below for these in your framework.

CVE-2026-33756 is a resource exhaustion vulnerability (CWE-770: Allocation of Resources Without Limits or Throttling) in the Saleor e-commerce platform. Affecting versions from 2.0.0 up to but excluding 3.23.0a3, 3.22.47, 3.21.54, and 3.20.118, the issue arises from Saleor's GraphQL query batching feature, which allows multiple operations to be submitted in a single HTTP request as a JSON array without enforcing an upper limit on the number of operations. This design permits attackers to bypass per-query complexity limits through excessive batch sizes.
Unauthenticated attackers can exploit this vulnerability remotely with low complexity and no privileges or user interaction required (CVSS v3.1: 7.5/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H). By crafting a single HTTP request containing a large number of GraphQL operations, they can overwhelm server resources, leading to denial-of-service conditions through resource exhaustion.
The vulnerability is addressed in Saleor releases 3.23.0a3, 3.22.47, 3.21.54, and 3.20.118. Mitigation details are provided in the following GitHub commit patches: https://github.com/saleor/saleor/commit/7be352fa8c35875d6e66d36493ca7c14c101bd64, https://github.com/saleor/saleor/commit/cdb66da97abb7c86939e384914cd8d9194f378e8, https://github.com/saleor/saleor/commit/d6a94e95bd77f3f733fa66afd1b1ac72e863ca2a, https://github.com/saleor/saleor/commit/e42aa4d6e588982e78942b033af051c8ec8f43fa, and https://github.com/saleor/saleor/commit/f0371bdd4cafcc841f1a9e7049cead6133bf7464. Organizations should upgrade to these versions promptly to prevent exploitation.

Vulnerability Data
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.

Mitigating Controls (NIST 800-53 r5) AI
Directly enforces a hard limit on concurrent sessions, structurally preventing unbounded resource allocation.
Requires explicit allocation of resources by priority or quota, directly stopping unlimited allocation.
Imposes a limit on consecutive invalid attempts, preventing one specific class of unbounded resource consumption.
Reduces impact of resulting DoS events without preventing the underlying lack of allocation limits.

Monitoring capacity and taking action to maintain availability directly reduces unchecked resource allocation.
Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
Baseline comparison of CPU, memory and bandwidth usage helps surface uncontrolled resource allocations before they cause service degradation.
Capacity projections and elasticity measures ensure that allocation requests are bounded and can be throttled, reducing the window in which an attacker can force unbounded resource reservations.
Defining retention periods and deletion schedules for backup copies prevents indefinite accumulation of data on storage media without corresponding resource-management controls.
Architectural redundancy and automatic failover limit the impact of an attacker who forces excessive allocations, because spare capacity can absorb the load until the primary instance recovers.
Documented incident response procedures that include activation of continuity plans and controlled recovery help ensure that resource consumption triggered by an incident is bounded and managed rather than left unbounded.
Mandating tested continuity procedures that preserve or replace resource-limiting controls prevents an attacker from exploiting the absence of throttling mechanisms during an outage.
