Description

This security bulletin contains information about 1 vulnerability.


1) Asymmetric Resource Consumption (Amplification) (CVE-ID: N/A)

CWE-ID: CWE-405 - Asymmetric Resource Consumption (Amplification)

CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to cause a denial of service by exhausting server CPU and memory resources.

The vulnerability exists due to asymmetric resource consumption in the graphql-go query executor when processing operations containing nested fragment spreads. A remote attacker can submit a crafted GraphQL operation that causes the same selections to be expanded repeatedly to exhaust server resources and interrupt service.
