Detailsinfo

A vulnerability classified as problematic has been found in MongoDB up to 8.0.27/8.2.11/8.3.6. This affects an unknown code block of the component JSON Schema. The manipulation of the argument jsonSchema with an unknown input leads to a resource consumption vulnerability. CWE is classifying the issue as CWE-400. The product does not properly control the allocation and maintenance of a limited resource, thereby enabling an actor to influence the amount of resources consumed, eventually leading to the exhaustion of available resources. This is going to have an impact on availability. The summary by CVE is:

Certain query operations involving deeply nested $jsonSchema constructs can trigger disproportionate CPU consumption in affected MongoDB deployments, potentially leading to resource exhaustion. The resulting CPU-bound operation cannot be interrupted through standard administrative controls.

The advisory is shared at jira.mongodb.org. This vulnerability is uniquely identified as CVE-2026-13064 since 06/23/2026. The exploitability is told to be easy. It is possible to initiate the attack remotely. Technical details are known, but no exploit is available. MITRE ATT&CK project uses the attack technique T1499 for this issue.
