Description

A security vulnerability has been identified in the GraphQL parser used by the API of s42.app. An attacker can overload the parser and cause the API pod to crash. With a bit of threading, the attacker can bring down the entire API, resulting in an unhealthy stream. This vulnerability can be exploited by sending a specially crafted request to the API with a large payload.

An attacker can exploit this vulnerability to cause a denial of service (DoS) attack on the s42.app API, resulting in unavailability of the API for legitimate users.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
