Description

This security bulletin contains information about 1 security vulnerability.


1) Missing Authorization (CVE-ID: CVE-2026-31800)

The vulnerability allows a remote attacker to read, modify, and delete GraphQL configuration and push audience data.

The vulnerability exists due to missing authorization in the generic /classes/_GraphQLConfig and /classes/_Audience REST API routes when handling requests for internal classes without master key authentication. A remote attacker can send crafted requests to these generic class routes to read, modify, and delete GraphQL configuration and push audience data.

This issue bypasses the master key enforcement present on the dedicated /graphql-config and /push_audiences endpoints.
