An attacker with low privileges could send high volumes of data without consuming responses, causing unbounded memory growth.

MEDIUM 4.3EPSS 0.23%

Does this matter?

Lower severity and a low EPSS score (0.23%). Track it; it rarely justifies an emergency change on its own.

Description

SAP Approuter does not enforce sufficient flow control in certain functionality. An attacker with low privileges could send high volumes of data without consuming responses, causing unbounded memory growth. This results in a low impact on availability. There is no impact on confidentiality and integrity.
